Neurons

How do memories last a lifetime when the molecules that form them turn over within days, weeks or months? An interaction between two proteins points to a molecular basis for memory.

The brain’s astounding cellular diversity and networked complexity could show how to make AI better.

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.

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.

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

The evolutionarily ancient part of the brain that controls breathing and heart rate also regulates the immune system — a discovery about the brain-body axis made by experts on taste.

Research suggests that psychedelic drugs can reopen critical periods of brain development to create opportunities for re-learning and psychological healing. In this episode, co-host Janna Levin speaks with Gül Dölen, a neuroscientist studying the therapeutic potential of psychedelic substances.
