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 […]

Tomorrow’s Anti-Anxiety Drug Is… Tylenol?

In this article for Scientific American, I talk about a new study that may have found an unusual use for a popular pain drug. Could Tylenol – also known by the drug name acetaminophen – really be the anti-anxiety drug of the future? If so, how would that work? Why would it work? And are […]

But fear not! Neuroscience knows how to cheer you up! Nope, this isn’t another […]

Stress Intervention

Scientists have discovered a way to shut down the brain’s “stress process” before it gets going, says a new study. By blocking the brain’s ability to manufacture certain chemicals called neurosteroids, researchers have managed to temporarily cut off a biological process crucial for stressful behavior – and for many stressful feelings as well. Animals from amphibians […]

Stress and Balance

Our responses to threatening situations depend on two fear-regulation circuits, a recent study shows. A well-balanced sense of fear is crucial to our survival: too much, and we’d descend into panic attacks every time we were startled. Too little, and we might not react when survival is crucial. As it turns out, this balance is maintained […]

Working Off Worry

Want to get rid of gloomy thoughts? Try working some physical activity into your daily routine, says a new study. For people who struggle with depression and anxiety, the research shows, exercise can be just as effective as antidepressant medication. It often prevents symptoms from getting worse – and in some cases, it even helps cure the problem. […]

Facing Fear

New neuroscientific studies are shedding light on the allure of dark forests and eerie old houses…and cliff diving. In psychology, this drive to explore the unusual is one manifestation of the behavior pattern known as “sensation-seeking” – the tendency to pursue intense, novel experiences out of curiosity, or just for the sheer joy of excitement.
