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 neuroscience. As we head into the next federal budget cycle, the future of the initiative remains uncertain. 

Today we take stock of how the BRAIN Initiative transformed neuroscience over the past 10 years, and what the outlook is for the future of the field.

To give us an unparalleled behind the scenes view, we are fortunate to have Bill Newsome with us on the show. A world renowned expert in the brain mechanisms of visual perception and decision-making, Bill co-chaired the original BRAIN Initiative planning committee in 2013 (the same year he became the founding director of the Wu Tsai Neurosciences Institute here at Stanford).

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 system in the brain called the "endocannabinoid" system (translation: the "cannabinoids within"). These somewhat exotic signaling molecules (made of fatty lipids and traveling "backwards" compared to other transmitters) have been deeply mysterious until recently, when new tools made it possible to visualize their activity directly in the brain.

So what is the "day job" of the endocannabinoid system — and how does it connect to the dramatic highs that come with taking THC or the medical benefits of CBD? 

To unpack all this, we're talking this week with neuroscientist Ivan Soltesz, the James Doty Professor of Neurosurgery and Neuroscience at Stanford, and a leading expert on the endocannabinoid system.

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 to remember in different locations within that space. When it's time to remember those things, you can mentally walk through that space and retrieve those items.

This ancient technique reveals something very fundamental about how our brains work. It turns out that the same parts of the brain are responsible both for memory and for navigating through the world.

Scientists are learning more and more about these systems and the connections between them, and it's revealing surprising insights about how we build the narrative of our lives, how we turn our environments into an internal model of who we are, and where we fit into the world.

Join us to learn more about the neuroscience of space and memory.

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, Stanford neurologist Mike Greicius, considers the new amyloid-clearing drugs a major disappointment — and worse, says they likely do more harm than good for patients.

Despite this critique, Greicius, thinks that the next few years will be an exciting time for novel Alzheimer’s therapies, as growing biological understanding of Alzheimer’s risk and resilience bear fruit with promising new approaches to treatment.

Greicius is the Iqbal Farrukh and Asad Jamal Professor of Neurology and Neurological Sciences at Stanford Medicine, and a member of the Knight Initiative for Brain Resilience and Alzheimer's Disease Research Center at 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 the Stanford Center for Precision Mental Health and Wellness and Vincent V.C. Woo Professor in the Stanford Department of Psychiatry and Behavioral Sciences.

Williams and her team have recently used brain imaging and machine learning techniques to identify six distinct "biotypes" of depression — each of which may require a different approach to treatment. Beyond setting the stage for more targeted therapies, better understanding the biology behind the disease could finally cut through the stigma of one of the world's most common brain disorders.

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 physically with the healthy brain tissue surrounding them, but the cancers actually need the brain's electrical activity to grow and spread.

It turns out that many cancers — not only in the brain — depend on nervous system innervation for their survival. Understanding this dependent relationship better may present an exciting new line of attack for oncology.

This week on From Our Neurons to Yours, we're talking about using new techniques for growing human brain tissue in the lab to solve a rare neurological disorder.

Host Nicholas Weiler sits down with Sergiu Pasca an innovative Stanford scientist who has developed groundbreaking technologies to grow human brain tissue in the lab, creating "organoids" and "assembloids" that model brain disorders like autism and schizophrenia. 

Pasca describes the process of turning patient skin cells into embryo-like stem cells and then into functional brain cells that can live and develop for over two years, and even be transplanted into rat brains to study their growth and development.

It may sound like science fiction, but these techniques represent a major step toward understanding and treating complex neurological conditions such as Timothy syndrome, a rare genetic disorder whose biology Pasca has spent the past 15 years unraveling. 

Join us for fascinating glimpse into the future of developmental neuroscience and  potential for new therapies for our remarkable self-assembling brains.

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 "radical behaviorist." Like other practitioners of cognitive behavioral therapy (CBT), she sees the troublesome thoughts and emotional states of many psychiatric disorders as just another form of behavior, which can be reshaped through self awareness and practice — much like you might work at avoiding junk food or not biting your nails.

Of course, one of the biggest challenges is the practice part. It's no easy task for patients to practice experiencing the world in a more positive, healthy way. This is why Bullock is eager for practitioners of CBT and related forms of psychotherapy to embrace virtual reality technologies — which enable psychiatrists to prescribe precisely calibrated "experiences" to treat cognitive & behavioral disorders.

We started by discussing early results from a clinical trial for a virtual reality-enhanced intervention major depressive disorder, which Dr. Bullock recently launched with support from the Wu Tsai Neurosciences Institute Neuroscience:Translate program.

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, flexible, and versatile as the skin itself.

Bao envisions a world where stick-on devices could help heal injuries, manage anxiety, and even enhance our perceptions, and soft, implanted devices could give neurosciences new insights into the workings of the body and brain.

In today’s episode, we talk about what makes the skin such an intriguing problem for an engineer like Bao; some of the many applications of her technology for medicine, neuroscience, and mental health; and its potential to enhance or extend our perceptions.

Bao is K.K. Lee Professor of Chemical Engineering at Stanford and founding director of eWEAR — the Stanford Wearable Electronics Initiative.

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 previously unknown form of plasticity:  Stanford psychiatry professor Rob Malenka (S1 E1 - Psychedelics and Empathy),  a pioneer in the study of synaptic plasticity and addiction, and neuro-oncologist Michelle Monje (S1 E12 - Brain Fog), who made some of the very first observations of myelin plasticity in the brain, essentially founding this field.

Together, they discuss their recent findings on the role of myelin plasticity in opioid addiction and its implications for understanding addictive behaviors.

Get ready to nerd out as we uncover a new angle on our brain's remarkable capacity for change.
