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 […]

Researchers “Copy and Paste” Fear From One Memory to Another

In this article for Discover Magazine, I explore a new set of experiments that sound like the plot of a bizarre sci-fi movie: Researchers taught a group of mice to fear a certain section of a maze, then electronically copied the mice’s fear from that memory and pasted it onto a different memory! How the hell did […]

Vampire Science: Young Blood Recharges Old Brains

In this article for Discover Magazine, I dig my teeth into a new set of experiments that seems almost supernatural: Injecting aging mice with blood from younger mice can reverse the aging process in their brains. Sounds like something straight out of a horror movie, doesn’t it? But its real, and it’s scientifically proven to […]

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 […]

The Top 5 Neuroscience Breakthroughs of 2013

If 2012 was the year neuroscience exploded into pop culture, 2013 was the year it stepped into the halls of power. The Obama administration’s $100-million BRAIN Initiative stirred up furious debate, as proponents cheered to see so much funding and press attention thrown at large-scale efforts to map the human brain, while opponents claimed that the […]

The Search for a Nobel Prize-Winning Synapse Machine

In this article for Scientific American, I talk with all three winners of 2013’s Nobel prize in physiology or medicine, about the paths that led them to victory. Where did their scientific careers start? Did they have any idea they’d be working in this area of research, let alone discover something as profound as they […]

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 […]

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 […]

Sexy Neuroscience IV

Every culture and subculture has its own rituals of greeting and affection – handshakes, backslaps, fist-bumps, hugs and so on – but when it comes to erotic contact, cultural differences seem to melt away into something more primal: Touch that just feels good for its own sake. In fact, a new study has confirmed that […]

“Learning How Brains Learn” — Podcast 9: Jeff Hawkins

On Episode 9 of the Connectome podcast, I’m joined by Jeff Hawkins, a computer engineer and neuroscience geek who’s obsessed with understanding how the brain learns. Jeff is the inventor of the Palm Pilot and the founder of Palm Computing – as well as another computing company called Handspring – but in addition to his […]
