This Is Your Brain on Magic Mushrooms

In this article for Discover Magazine, I take a trip into the weird world of psychedelic neuroscience – which is actually a major area of serious research right now. Specifically, I delve into one new fMRI study, which found that psilocybin, the active ingredient in psychedelic mushrooms, changes brain connectivity in two very distinct ways. Could this have […]

Brain-Wide Map of “Neural Highways” Is First of Its Kind

In this article for Scientific American, I report on a new map of neural connections among just about every area of the cerebrum. What does this map mean, exactly? Where does the data come from? What does it tell us about how the brain works? And how can we use it to help treat brain […]

Brains of Autistic Children Are Surprisingly Hyper-Connected

In this article for Discover Magazine, I explore a new study that’s found a new difference in the brains of autistic children: Different brain regions aren’t actually under-connected, as some researchers have believed – they’re actually hyper-connected, exchanging information much more than they would in a non-autistic brain. What does this mean? Could it point toward […]

Connectome

The Neuroscience Revolution Will Be Crowdsourced

In this article for Scientific American, I dig into one of my very favorite scientific projects: The Human Connectome Project at MIT. What’s the deal with all this excitement? What exactly are these researchers trying to accomplish? And how close are they to accomplishing it? The answers to all these questions may surprise you. Once humans […]

The largest scale effort is the Human Connectome Project, involving a consortium of institutions here and abroad

Why Brain-Mapping Efforts Matter

In this article for Scientific American, I tackle some common criticisms of big brain-mapping projects like the Human Connectome Project and the Brain Activity Map. Are they too complex to be feasible in our lifetimes? Maybe so. Do we even know exactly what we’re trying to achieve? It isn’t always precisely clear. But I argue […]

“Senses That Bleed” — Podcast 5: David Eagleman

On episode 5 of the Connectome podcast, I chat with David Eagleman, author of the international bestseller Incognito: The Secret Lives of the Brain. Eagleman’s lab mainly studies the ways our brains encode sensory perceptions – but as you’ll hear, he’s also fascinated by questions on the nature of consciousness, synesthesia, meaning and representation, and […]

“Using Worms to Crack the Human Brain” — Podcast 4: Scott Emmons

On episode 4 of the Connectome podcast, I chat with Scott W. Emmons, Ph.D., a professor of neuroscience and genetics at Albert Einstein College of Medicine. Dr. Emmons talks about his cutting-edge connectomics research, which may help us understand how neural circuits “decide” on a particular behavior. Though his recent work focuses on the nervous […]

The Lurking Lizard

He has haunted us for more than fifty years – this strange scientist, with his theory of primal reptiles embedded in each of us. And for years I wondered, Could this bizarre hypothesis be true? Might it explain the ancient instincts – so contrary to my intentions – which I felt arising from the depths […]

Brains and Brilliance

Where in the brain, exactly, is intelligence? Is a high I.Q. just a result of a flawed test – or do high-I.Q. brains have specific, measurable differences from others? Answers await, Intrepid Reader – but first we have to make sure we’re asking the right questions. Let’s start with the big news: a study just published […]

The Intelligence Network

Intelligence isn’t a single process – but it still depends on the coordinated activity of some specific brain areas, a new study reports. In one of the most sweeping surveys in neuroscience history, researchers put patients with various types of brain damage through a battery of cognitive tests, and pinpointed the neural correlates of “general […]
