The release of a single signaling chemical from a specific nerve-cell tract in a particular part of the brain, like an on/off switch, may spell the difference between sociability and social awkwardness.

Neurons in the brain and body send chemical signals from one to the next. Now, scientists led by Stanford's Steven Chu are a step closer to watching those signals take shape inside individual neurons.

Stanford psychiatric researcher Natalie Rasgon, MD, PhD, and her collaborators in a multicenter study have identified a substance, acetyl-L-choline, whose levels in the blood of people suffering from depression are correspondingly depressed.

Investigators at Stanford and elsewhere have shown, for the first time in humans, that low blood levels of acetyl-L-carnitine track with the severity and duration of depression.

Stanford neuroscientist Lisa Giocomo, PhD, and her colleagues examined the navigational behavior and brain-activity patterns of mice traveling through a virtual reality environment.

Your brain doesn't just sits still inside your skull, it rhythmically bulges and shrinks with each heartbeat, by an amount equivalent to a bit less the width of a human hair.

For years, the people developing artificial intelligence drew inspiration from what was known about the human brain, and it has enjoyed a lot of success as a result. Now, AI is starting to return the favor.

Parkinson's disease affects millions of people worldwide, slowing their movements and making it difficult to walk, but exactly how Parkinson's works remains a bit mysterious.

In the new study, a team directed by Stanford neuroscientist Andy Huberman, PhD, unraveled the brain circuitry that fine tunes the fright-flight-or-fight response to a visually perceived threat.

Stanford researchers set out to test a seminal theory of Parkinson’s disease and several related conditions. What they found is more complex than anyone had imagined.

Pinpoint stimulation of a cluster of nerve cells in the brains of mice encouraged timid responses to a perceived threat, whereas stimulation of an adjacent cluster induced boldness and courage.

By converting brain waves into sound, even non-specialists can detect “silent seizures” – epileptic seizures without the convulsions most of us expect.

Tiny lab-grown blobs could aid understanding of psychiatric and neurological disease

A new study finds that young children’s brains have not yet fully developed the vision circuits they need to understand words and recognize faces, a finding that could help in understanding how children learn to read.

Mentally running through a routine improves performance, but how that works isn’t clear. Now, a new tool — brain-machine interface — suggests the answer lies in how our brains prepare for action.
