Studies of sleep are usually neurological. But some of nature’s simplest animals suggest that sleep evolved for metabolic reasons, long before brains even existed.
A newfound hub of immune system activity at the back of the brain solves a century-old puzzle.
Some populations of neurons simultaneously process sensations and memories. New work shows how the brain rotates those representations to prevent interference.
The learning algorithm that enables the runaway success of deep neural networks doesn’t work in biological brains, but researchers are finding alternatives that could.
By digging out signals hidden within the brain’s electrical chatter, scientists are getting new insights into sleep, aging and more.
Catherine Dulac is overturning preconceptions about “male” and “female” instincts and opening new avenues to treating postpartum depression.
Researchers see structural changes in genetic material that allow memories to strengthen when remembered.
Deep neural networks, often criticized as “black boxes,” are helping neuroscientists understand the organization of living brains.
