From Our Neurons to Yours
This award-winning show from Stanford’s Wu Tsai Neurosciences Institute is a field manual for anyone who wants to understand their own brain and the new science reshaping how we learn, age, heal, and make sense of ourselves. Each episode, host Nicholas Weiler sits down with leading scientists to unpack big ideas from the frontiers of the field—brain-computer interfaces and AI language models; new therapies for depression, dementia, and stroke; the mysteries of perception and memory; even the debate over free will. You’ll hear how basic research becomes clinical insight and how emerging tech might expand what it means to be human.
Episodes
A new precision neuroscience of language (Big Ideas in Neuroscience) | Cory Shain
Right now, as you're reading this sentence, something remarkable is happening in your brain. Light waves from your screen hit your eyes, transform into electrical signals, and take on meaning. You understand what you're reading. This is language — our human superpower.But despite 150 years of intensive research, we still do not have a complete picture of how the brain actually accomplish
How childhood (and Pokémon) shape how we see the world | Kalanit Grill-Spector
Today's episode is all about how childhood literally shapes the brain.Our most important experiences – from learning to read, to the growing complexity of our social lives at school, and even the video games we play – leave physical traces in how our brains get organized that shape how we see the world as adults.But how does the brain actually know what parts of our lives are actually importa
The FDA's psychedelic sea-change: what accelerated clinical trials for psilocybin, methylone, and ibogaine mean for mental health and neuroscience research | Boris Heifets
Last month we saw a big shift in the federal government’s approach to psychedelic medicine.Specifically, following an executive order by President Trump, the FDA announced it is fast-tracking its review of several clinical trials of psychedelic drugs for patients with mental health disorders. The executive order also directed more funds towards psychedelic research and a review of psychedelics’ st
Will work for dopamine: why hard work motivates us | Neir Eshel
Today’s episode is about the neuroscience of hard work—or maybe more specifically, the value we place on hard work.There’s something different about hiking to the top of a mountain versus taking a helicopter. The view from the top is exactly the same, but if you’ve done the hard slog to get there, the payoff is going to be much more rewarding. The question is, how does the brain know the differenc
Could Parkinson's start in the gut? | Kathleen Poston
Traditionally, we think of Parkinson's as a movement disorder—defined by slowed movement, stiff muscles, and involuntary shaking. But it turns out there are other symptoms that appear years or even decades before movement problems bring patients to the clinic: sleep disturbances, chronic constipation, and loss of smell.For today's guest, these early symptoms represent an incredible oppor
Big Ideas: How see-through brains could transform neuroscience | Guosong Hong
What if we could make the brain see-through? It sounds like science fiction, but it could revolutionize how we study the brain. Today on the show, we're talking with Guosong Hong, a faculty scholar here at the Wu Tsai Neurosciences Institute who has a unique reputation for developing creative techniques that literally shed light on the brain—from using fluorescent nanomaterials and focused ul
Could boosting gut–brain communication prevent memory loss? A tale of microbes, memory, and our internal senses | Christophe Thaiss
Our memories and senses are deeply connected—like how a favorite song can recreate a whole glorious teenage summer. It turns out this relationship might extend beyond our five external senses to include our internal senses: the signals telling us what's happening inside our bodies, sometimes beyond the veil of conscious perception.New research by Wu Tsai Neurosciences Institute affiliate Chri
Why do some of us age faster than others? | Claire Bedbrook and Ravi Nath
Today on the show, why do some of us age faster than others? Why do some of us grow old and die before our time while others seem to simply endure? And most of us have probably wondered at one point or another, which track am I on? Turns out it might be possible to predict the whole trajectory of an animal's life at a surprisingly young age, just by looking closely at subtle patterns of behav
Big Ideas in Neuroscience: A new neuroscience of pregnancy | Nirao Shah & Katrin Svensson
We know shockingly little about what goes on in a mother’s brain during pregnancy.For example, we know only a handful of the hormones involved—out of hundreds scientists think may exist—and very little about how they might impact the brain. This gap in our understanding is one of the reasons we don’t have great treatments for pregnancy-related maladies, whether it’s extreme nausea, or anxiety and
Why do our minds wander? What the brain's default mode tells us about our humanity | Vinod Menon
Here’s a question for you that may at first seem trivial, but is actually profound: Why do our minds drift? If you have ever dabbled in mindfulness or meditation, you know this mind wandering has an almost gravitational pull. In fact, researchers now think we spend as much as 50 percent of our waking time in this state, which cognitive scientists have dubbed the brain’s “default mode.”Today’s gues
Is Alzheimer's an energy crisis in the brain? Inflammation, metabolism and a new path in the search for cures | Kati Andreasson
For decades, Alzheimer's research has focused on clearing amyloid plaques from the brain. But new drugs that successfully remove plaques have proven clinically "underwhelming", leaving the field searching for alternative approaches.Stanford neurologist Katrin Andreasson has spent twenty years pursuing a different path—investigating how aging triggers an energy crisis in the brain&ap
"The Emergent Mind: How Intelligence Arises in People and Machines" | Jay McClelland
The AI revolution of the past few years is built on brain-inspired neural network models originally developed to study our own minds. The question is, what should we make of the fact that our own rich mental lives are built on the same foundations as the seemingly soulless chat-bots we now interact with on a daily basis?Our guest this week is Stanford cognitive scientist Jay McClelland, who has be
Could brain implants read our thoughts? | Erin Kunz
Imagine what it’s like to lose your ability to speak. You know what you want to say, but the connection between your brain and the muscles that form words is no longer functioning. For people with conditions like ALS, or who experience a severe stroke, this is a devastating reality. Today's guest is Erin Kunz, a postdoctoral researcher in the Neural Prosthetics Translational Laboratory at Sta
NeuroForecasting: how brain activity can predict stock prices or viral videos | Brian Knutson
Neuroscientists have spent the past few decades tracing the network of brain systems—some deep and emotional, and others more analytical and deliberate— that work together as we make tough choices like where to invest our money as well as more everyday decisions like which videos to watch online—or, for that matter, which podcast to listen to.You can imagine that the ability to listen in on the br
"Why Brains Need Friends: The Neuroscience of Social Connection" | Ben Rein
We are more isolated from one another than ever before — by our technology, by our political divides, and most of all, by our choices. This week on the show, we talk with neuroscientist Ben Rein about why this social isolation is terrible for our health — implicated in not only rising rates of mental illness, but also heart disease, dementia and more.We discuss Ben's new book, "Why Brain
From doodles to Descartes: sketching and the human cognitive toolkit | Judith Fan
Before the written word — and possibly even before speech — humans have communicated through drawing. From crude scratches in the dirt or on cave walls to the arcane symbology of the laboratory whiteboard, our instinct for conveying our thoughts visually is pretty extraordinary. We see or understand something in the world, we build an idea in our mind of what we think we see, and then using our ha
What is psychosis? Navigating an altered reality | Jacob Ballon & Shannon Pagdon
Imagine if you couldn't distinguish between dreams and reality. If you couldn't tell whether what you were seeing or hearing was really there in front of you. What if you discovered you couldn't trust your own perceptions? Psychosis is something three out of every a hundred people will experience at some point in their lifetimes. But what exactly is it, and is it something people ca
"I Heard There Was a Secret Chord: Music as Medicine" | Daniel Levitin
Most of us can agree: music is awesome. Regardless of which songs speak to you, music probably plays an important role in your life. The question is, what makes music so powerful? Why does a particular combination of sounds and rhythms grab us and affect us in the way that it does? And is it true that music can help heal patients with Alzheimer's, Parkinson's, PTSD, chronic pain, and mor
How we learn to read (and why some struggle): what neuroscience teaches us about a transformative human technology | Bruce McCandliss
In this episode, we explore the fascinating neuroscience behind how children learn to read with Bruce McCandliss, director of the Stanford Educational Neuroscience Initiative.Key topics include:• How our brains "recycle" visual and language circuits to create reading expertise• The crucial threshold when reading shifts from effortful to automatic• Why some children struggle more than oth
Why voices light us up—but leave the autistic brain in the dark | Dan Abrams
Recognizing a familiar voice is one of the brain’s earliest social feats. But what are the brain circuits that let a newborn pick out mom in a crowded nursery? How do they change as kids turn toward friends and the wider world? And what are we learning about why this instinct fails to develop in the autistic brain?This week, host Nicholas Weiler joins Stanford neuroscientist Dan Abrams on the ques
Famous & Gravy: Cosmic Marketer and the Meaning of Life | Stephen Hawking
In this special crossover episode, we’re doing something a little different. From Our Neurons to Yours host Nicholas joins producer Michael Osborne to co-host his podcast Famous and Gravy for a lively conversation about the extraordinary life and mind of Stephen Hawking.Hawking, one of the most renowned scientists of our time, lived with ALS for more than 50 years—defying medical expectations whil
Can brain science save addiction policy? | Keith Humphreys
If addiction is a disease of the brain, what does that mean for how we treat people—and how we write policy? In this wide-ranging conversation, Stanford addiction expert and policy advisor Keith Humphreys returns to the show to walk us through what neuroscience has taught us about substance use disorders and how that science intersects with law, public health, and politics.From the biology of crav
How basic science transformed stroke care | Marion Buckwalter
A generation ago, a big clot in the brain meant paralysis or worse. Today, doctors can diagnose clots on AI-enabled brain scans; provide life-saving, targeted medications; or snake a catheter from a patient’s groin into the brain to vacuum out the clot. If they intervene in time, they can watch speech and movement return before the sedatives wear off. How did that happen—and what’s still missing?I
Surgery as a window into brain resilience | Martin Angst
We've all heard stories about someone who went in for surgery and came out...different. A grandmother who struggled with names after hip replacement, or an uncle who seemed foggy for months following cardiac bypass. But why does this happen to some people while others bounce right back?This week, we explore this question with Dr. Martin Angst, a professor of anesthesiology at Stanford who&apo
Best of: How neural prosthetics could free minds trapped by brain injury | Jaimie Henderson
Imagine being trapped in your own body, unable to move or communicate effectively. This may seem like a nightmare, but it is a reality for many people living with brain or spinal cord injuries.We're re-releasing one of our favorite episodes from the archives: our 2024 conversation with Jaimie Henderson, a Stanford neurosurgeon leading groundbreaking research in brain-machine interfaces. Hende
The secrets of resilient aging | Beth Mormino & Anthony Wagner
This week on the show, we're have our sights set on healthy aging. What would it mean to be able to live to 80, 90 or 100 with our cognitive abilities intact and able to maintain an independent lifestyle right to the end of our days? We're joined by Beth Mormino and Anthony Wagner who lead the Stanford Aging and Memory Study, which recruits cognitively healthy older adults to understand
Building AI simulations of the human brain | Dan Yamins
This week on the show: Are we ready to create digital models of the human brain? Last month, Stanford researcher Andreas Tolias and colleagues created a "digital twin" of the mouse visual cortex. The researchers used the same foundation model approach that powers ChatGPT, but instead of training the model on text, the team trained in on brain activity recorded while mice watched action m
What ChatGPT understands: Large language models and the neuroscience of meaning | Laura Gwilliams
If you spend any time chatting with a modern AI chatbot, you've probably been amazed at just how human it sounds, how much it feels like you're talking to a real person. Much ink has been spilled explaining how these systems are not actually conversing, not actually understanding — they're statistical algorithms trained to predict the next likely word. But today on the show, let&apo
What the other half of the brain does | Brad Zuchero
We've talked about glia and sleep. We've talked about glia and neuroinflammation. We've talked about glia in the brain fog that can accompany COVID or chemotherapy. We've talked about the brain's quiet majority of non–neuronal cells in so many different contexts that it felt like it was high time for us to take a step back and look at the bigger picture. After all, glia sc
Stimulating the brain with sound | Kim Butts Pauly and Raag Airan
As we gain a better understanding of how misfiring brain circuits lead to mental health conditions, we'd like to be able to go in and nudge those circuits back into balance. But this is hard — literally — because the brain is encased in this thick bony skull. Plus, often the problem you want to target is buried deep in the middle of a maze of delicate brain tissue you need to preserve.Today w
Does good sleep insulate the brain against Alzheimer's? | Erin Gibson
We're kicking off our new season with a deep dive into one of neuroscience's most fascinating mysteries: sleep. This unconscious third of our lives isn't just about rest – it's absolutely critical for brain health, memory consolidation, and overall well-being. But here's where it gets intriguing: recent research suggests that increased napping as we age might be an early w
How to live in a world without free will | Robert Sapolsky
Today, we are speaking with the one and only Robert Sapolsky, a Stanford neurobiologist, a MacArthur "Genius", and best-selling author of books exploring the nature of stress, social behavior, and — as he puts it — "the biology of the human predicament." In his latest book, Determined, Sapolsky assertively lays out his vision of a world without free will — a world where as much
The power of psychedelics meets the power of placebo: ketamine, opioids, and hope in depression treatment | Boris Heifets & Theresa Lii
Join us as we dive back into the world of psychedelic medicine with anesthesiologists Boris Heifets and Theresa Lii, who share intriguing new data that sheds light on how ketamine and placebo effects may interact in treating depression.We explore provocative questions like: How much of ketamine's antidepressant effect comes from the drug itself versus the excitement of being in a psychedelics
Seeing sounds, tasting colors: the science of synaesthesia with David Eagleman (re-release)
Today, we are going back into the archives for one of my favorite episodes: We are talking to neuroscientist, entrepreneur, and best-selling author, David Eagleman. We're talking about synaesthesia — and if you don't know what that is, you're about to find out.Special NoteWe are beyond thrilled that From Our Neurons to Yours has won a 2024 Signal Award in the Science Podcast categor
The BRAIN Initiative: the national vision for the future of neuroscience is now in doubt | Bill Newsome
Earlier this year, President Obama's signature BRAIN Initiative, which has powered advances in neuroscience for the past 10 years, had its budget slashed by 40%. Over the past decade, the BRAIN Initiative made roughly $4 billion in targeted investments in more than 1500 research projects across the country and has dramatically accelerated progress tackling fundamental challenges in neuroscien
The cannabinoids within: how marijuana hijacks an ancient signaling system in the brain | Ivan Soltesz
Given the widespread legalization of cannabis for medical and recreational uses, you'd think we'd have a better understanding of how it works. But ask a neuroscientist exactly how cannabinoid compounds like THC and CBD alter our perceptions or lead to potential medical benefits, and you'll soon learn just how little we know.We know that these molecules hijack an ancient signaling sy
Memory Palaces: the science of mental time travel and the brain's GPS system | Lisa Giocomo (Re-release)
Today we are re-releasing an episode we did last year with Stanford neurobiologist Lisa Giocomo exploring the intersection of memory, navigation and the boundaries we create between ourselves and the world around us.This episode was inspired by the idea of memory palaces. The idea is simple: Take a place you're very familiar with, say the house you grew up in, and place information you want t
Why new Alzheimer's drugs don't work | Mike Greicius, Stanford University School of Medicine
In the past few years, Big Pharma has released not one, but three new treatments for Alzheimer’s disease. Aducanemab (2021), Lecanemab (2023), and Donanemab (2024), are the first treatments to effectively clear the brain of amyloid plaques — the sticky protein clumps whose build-up in the brain has defined the disease for decades. The problem? They may not help patients at all.Today’s guest, Stanf
Depression's distinctive fingerprints in the brain | Leanne Williams, Stanford University
Getting help for depression can be like purgatory. Setting aside for a moment the stigma and other barriers to seeking treatment in the first place, finding the right combination of medication and/or therapy can be a months- or years-long process of trial and error. And for about one third of people, nothing seems to work.Today we're talking with Dr. Leanne Williams, the founding director of
How the brain helps cancers grow | Michelle Monje
Today, we're talking with Stanford neuro-oncologist, Michelle Monje. This is actually the third time we've had Michelle on the show, in part because she's been a pioneer of three exciting frontiers in neuroscience — so far! This week, we're going to talk about cancer neuroscience. Michelle founded this new field with her discovery that deadly brain tumors not only link up physi
Unraveling Timothy Syndrome: the new science of human brain development | Sergiu Pasca

How VR could help treat depression with "radical behaviorist" Dr. Kim Bullock
Today, we're going to talk about virtual reality and how it could be used to treat depression. We're talking with psychiatrist Kim Bullock, the founding director of Stanford's Neurobehavioral Clinic and Virtual Reality & Immersive Technologies (VRIT) program. Dr. Bullock — a physician certified in Neuropsychiatry, Psychiatry, and Lifestyle Medicine — calls herself a "radica
Electronic skin and the future of wearable technology | Zhenan Bao
The skin is full of contradictions. It’s soft and sensitive, but also tough and resilient, even self-healing. It’s both the barrier that protects us from infections and our most intimate connection with the outside world. Today’s guest, Zhenan Bao, has spent the last two decades reverse engineering the skin’s many remarkable properties in order to create wearable electronics that are just as soft,
How a new kind of brain plasticity could help make sense of addiction | Michelle Monje and Rob Malenka
This week, we're diving into recent research that sheds light on a new form of brain plasticity involving changes in the insulation of nerve fibers — called myelin. It turns out that myelin plasticity is implicated in a number of serious conditions, from epilepsy to drug abuse and addiction.We're excited to bring back two previous guests on the show to share their insights on this previ

Neuroscience and AI: What artificial intelligence teaches us about the brain (and vice versa) | Surya Ganguli
The powerful new generation of AI tools that has come out over the past few years — DALL-E, ChatGPT, Claude, Gemini, and the rest — have blown away our old ideas about what AI can do and raised questions about what it means for computers to start acting... intelligent?This week, we ask what the rise of these systems might teach us about our own biological intelligence — and vice versa. What does
How we remember, why we forget | Anthony Wagner
At some point in our lives, we all struggle with memory — learning a new name, remembering that book you were reading just yesterday or that word on the tip of your tongue. So what can neuroscience teach us about why we remember, why we forget, and how we might even improve our memories? To answer this question, I spoke with neuroscientist Anthony Wagner, a memory expert in Stanford's Departm
Psychedelics Part 2: How do drugs alter our perceptions? | Boris Heifets
Today, we're going to talk about how psychedelics alter our perception of reality and what that says about... reality! Welcome to part two of our conversation with Stanford anesthesiologist and psychedelics researcher Boris Heifets! Last time, we talked with Boris about the question of why psychedelics help people with mental health disorders. This week, we're going to dive into a diffe
Psychedelics, placebo, and anesthetic dreams | Boris Heifets (part 1)
Psychedelics are a hot topic in psychiatry today. They’re producing dramatic reversals for patients with severe depression, PTSD, and other mental health conditions. But scientists still have fundamental questions about why these drugs are so effective. For example, is the "trip" even necessary? Some think it is not and are working to design drugs with similar brain chemistry but no psy
Why our brains are bad at climate change | Nik Sawe
This week on From Our Neurons to Yours, we're talking about the neuroscience of climate change with neuroeconomist Nik Sawe.If you follow the science or the news, you know how big of a risk climate change is. Storms, coastal flooding, heat waves, extinctions, mass migration — the list goes on. But — as you can probably also appreciate — it’s really hard to properly perceive that risk. It’s mu
Famous & Gravy: Mind Traveler | Oliver Sacks
This week we’re doing something a little different. My good friend Michael Osborne, who produces this show also has his own podcast, called Famous & Gravy – Life Lessons from Dead Celebrities.I recently guest-hosted an episode about one of my all time scientific and writerly heros, Oliver Sacks, which we're releasing for both our audiences. I hope you enjoy!---We've concluded Season
The clocks in your body | Tony Wyss-Coray
Today: the clocks in your body.We're talking again this week with Tony Wyss-Coray, the director of the Knight Initiative for Brain Resilience here at Wu Tsai Neuro. Last year, we spoke with Tony about the biological nature of the aging process. Scientists can now measure signs of aging in the blood, and can in some cases slow or reverse the aging process in the lab. We discussed how this biol
Redefining Parkinson's Disease | Kathleen Poston
Today on the show, a new understanding of Parkinson's disease. Parkinson's disease is one of the most common neurodegenerative disorders — right after Alzheimer's disease. It's familiar to many as a movement disorder: people with the disease develop difficulties with voluntary control of their bodies. But the real story is much more complicated.This week, we speak with Kathleen
Space and Memory | Lisa Giocomo
This week on From Our Neurons to Yours, we sit down with Stanford neurobiologist Lisa Giocomo to explore the intersection of memory and navigation. This episode was inspired by the idea of memory palaces. The idea is simple: Take a place you're very familiar with, say the house you grew up in, and place information you want to remember in different locations within that space. When it's
OCD & Ketamine | Carolyn Rodriguez
In this episode of "From Our Neurons to Yours," we're taking a deep dive into the neuroscience of obsessive-compulsive disorder (OCD) and the recent discovery that the anesthetic ketamine can give patients a week-long "vacation" from the disorder after just one dose.Join us as we chat with Dr. Carolyn Rodriguez, a leading expert in the field, who led the first clinical tri
Why we do what we do | Neir Eshel

Brain-Machine Interfaces | Jaimie Henderson
Imagine being trapped in your own body, unable to move or communicate effectively. This may seem like a nightmare, but it is a reality for many people living with brain or spinal cord injuries. Join us as we talk with Jaimie Henderson, a Stanford neurosurgeon leading groundbreaking research in brain-machine interfaces. Henderson shares how multiple types of brain implants are currently being devel
An electrical storm in the brain | Fiona Baumer
Imagine an electrical storm in your brain, a power surge that passes through delicately wired neural circuits, making thousands of cells all activate at once. Depending on where it starts and where it travels in the brain, it could make your muscles seize up. It could create hallucinatory visions or imaginary sounds. It could evoke deep anxiety or a sense of holiness, or it could even make you los
Seeing sound, tasting color | David Eagleman
Imagine Thursday. Does Thursday have a color? What about the sound of rain — does that sound taste like chocolate? Or does the sound of a saxophone feel triangular to you? For about 3% of the population, the sharp lines between our senses blend together. Textures may have tastes, sounds, shapes, numbers may have colors. This sensory crosstalk is called synesthesia, and it's not a disorder, ju
Why sleep keeps us young | Luis de Lecea
Welcome back, neuron lovers! In this week's episode of From Our Neurons to Yours, we're talking about the neuroscience of sleep. Why is slumber so important for our health that we spend a third of our lives unconscious? Why does it get harder to get a good night's sleep as we age? And could improving our beauty rest really be a key to rejuvenating our bodies and our minds?To learn
Where ant colonies keep their brains | Deborah Gordon
Welcome back to "From Our Neurons to Yours," a podcast from the Wu Tsai Neurosciences Institute at Stanford University.

In this episode, we explore how sound becomes information in the human brain, specifically focusing on how speech is transformed into meaning. Our guest this week is Neuro-linguist Laura Gwilliams, a faculty scholar at t
Exercise and the brain | Jonathan Long
We all know exercise has all sorts of benefits beyond just making us stronger and fitter. It lowers and inflammation. It buffers stress and anxiety. It clarifies our thinking. In fact, regular exercise is one of the few things we know with reasonable confidence can help extend our healthy lifespan. But for all the evidence of the benefits of exercise, it's a bit surprising that we don't
Aging and Brain Plasticity | Carla Shatz
When we're kids, our brains are amazing at learning. We absorb information from the outside world with ease, and we can adapt to anything. But as we age, our brains become a little more fixed. Our brain circuits become a little less flexible. You may have heard of a concept called neuroplasticity, our brain's ability to change or rewire itself. This is of course central to learning and m
Brain stimulation & "psychiatry 3.0" | Nolan Williams
Transcranial magnetic stimulation (TMS) is a technology that uses magnetic fields to stimulate or suppress electrical activity in brain circuits. It's part of a transformation in how psychiatrists are thinking about mental health disorders that today's guest calls psychiatry 3.0. Nolan Williams has recently pioneered a new form of TMS therapy that has just been approved by the FDA to tre
Brain Fog | Michelle Monje
One of the strangest and most disconcerting things about the COVID 19 pandemic has been the story of long COVID.Many COVID long-haulers have continued experiencing cognitive symptoms long after their initial COVID infection — loss of attention, concentration, memory, and mental sharpness — what scientists are calling "brain fog". For some patients, the condition is so serious that it c
Assembling the brain | Sergiu Pasca
Nearly one in five Americans lives with a mental illness. Unfortunately there’s a limited set of options for treating psychiatric disorders. One reason for that is that these disorders are still defined based on people’s behavior or invisible internal states — things like depressed mood or hallucinations. But of course, all our thoughts and behaviors are governed by our brains. And there’s a lot
Parenting Lessons from Frogs and Spiders | Lauren O'Connell
Today we’re going to talk about frogs — and spiders — as parents. What today’s show is really about is “pair bonding” — that’s the scientific term for the collaborative bonds that form between two parents — as well as the bonds between parents and their offspring. It turns out that if you look across the animal kingdom, strong family bonds are way more widespread than you might imagine. Frogs have
Virtual Touch | Allison Okamura
Recently on the show, we had a conversation about the possibility of creating artificial vision with a bionic eye. Today we're going to talk about technology to enhance another sense, one that often goes underappreciated, our sense of touch. We humans actually have one of the most sensitive senses of touch on the planet. Just in the tip of your fingers, there are thousands of tiny sensors, wh
Brain Rejuvenation | Tony Wyss-Coray
Hi listeners, we're shifting to a biweekly release schedule after this episode. See you in a couple weeks!---Most of us probably know someone who developed Alzheimer’s disease or another form of dementia as they got older. But you probably also know someone who stayed sharp as a tack well into their 80s or 90s. Even if it’s a favorite TV actor, like Betty White. The fact that people age so di
Building a bionic eye | EJ Chichilnisky
We take this for granted, but our eyes are amazing. They're incredible. We process the visual world so automatically and so instantaneously, we forget how much work our eyes and our brains are doing behind the scenes, taking in light through the eyeball, transforming light into electrical signals in the retina, packaging up all that information, and sending it on to the brain, and then making
Respect your Biological Clock | Erin Gibson
We've probably all heard of circadian rhythms, the idea that our bodies have biological clocks that keep track of the daily cycle, sunrise to sunset. Maybe we've even heard that it's these biological rhythms that get thrown off when we travel across time zones or after daylight savings.So on one hand, it's cool that our body keeps track of what time it is, but today our questio
Is Addiction a Disease? | Keith Humphreys
What makes addiction a disease? I think we all know at this point that addiction is another major epidemic that is sweeping our country and the world, but there are few topics that are more misunderstood than addiction. In fact, some people question whether addiction is even truly a disease. To delve into this question of why neuroscientists and health policy experts do think of addiction as a di
Your gut - the second brain? | Julia Kaltschmidt
You may have heard the idea that the gut is the second brain, but what does that really mean? Maybe it has to do with the fact that there are something like 100 to 600 million neurons in your gut. That's a lot of neurons. That's about as many as you'd find in the brain of say, a fruit bat, or an ostrich, or a Yorkshire Terrier. And it turns out, this network of intestinal neurons,
The Octopus Brain | Ernie Hwaun & Matt McCoy
What can octopus and squid brains teach us about intelligence?One of the incredible things about octopus's is that not only do they have an advanced intelligence that lets them camouflage themselves, use tools and manipulate their environments and act as really clever hunters in their ecosystems, they do this with a brain that evolved essentially from something like a slug in the oceans hundr
The Mystery of Migraines | Gabriella Muwanga
If you've ever had a migraine, you know that the symptoms — splitting headache, nausea, sensitivity to light — mean you're going to want to spend some time in bed, in a dark room. Migraines are flat out debilitating, and the statistics back this up.Migraines are the third most common neurological disorder. They affect as many as a billion people around the world, making them one of the w
Psychedelics and Empathy | Rob Malenka
