Neuroscience

Every soft caress of wind, searing burn and seismic rumble is detected by our skin’s tangle of touch sensors. David Ginty has spent his career cataloging the neurons beneath everyday sensations.

Complex neural pathways likely arose independently in birds and mammals, suggesting that vertebrates evolved intelligence multiple times.

A popular hypothesis for how the brain clears molecular waste, which may help explain why sleep feels refreshing, is a subject of debate.

By screening films in a brain scanner, neuroscientists discovered a rich library of neural scripts — from a trip through an airport to a marriage proposal — that form scaffolds for memories of our experiences.

Individual cells in the brain light up for specific ideas. These concept neurons, once known as “Jennifer Aniston cells,” help us think, imagine and remember episodes from our lives.

Biologists used artificial intelligence to make discoveries about molecules and the brain, and overturned long-held assumptions about the immune system and RNA.

We often consider spoken language to be a feature that distinguishes humans from other forms of animal life. Brain research, however, suggests that other creatures — including certain birds — share some of our neural circuitry related to language. In this episode, co-host Janna Levin explores the origins and underlying mechanisms of human speech and birdsong with neurobiologist and geneticist Erich Jarvis.

Zero, which was invented late in history, is special among numbers. New studies are uncovering how the brain creates something out of nothing.

Like a highway system, the vagus nerve branches profusely from your brain through your organs to marshal bodily functions, including aspects of mind such as mood, pleasure and fear.
