A newly identified group of amygdala neurons appears to play a central role in anxiety and social behavior. Restoring normal activity in this tiny brain circuit reversed anxiety and social deficits in mice, revealing...

Scientists have uncovered evidence that autism may include at least two biologically distinct subtypes, each marked by a different pattern of brain communication. By combining brain scans from nearly 1,000 people with...

A major study suggests that some of the groundwork for brain development may be shaped before birth through a surprising partnership between a baby’s genes and gut microbes. Researchers found that epigenetic changes...

Researchers found that social behavior begins in the brain before it becomes visible as movement. In zebrafish, a coordinated pattern of activity spread across the brain several seconds before the animals approached...

Scientists at Scripps Research have uncovered a molecular “switch” that appears to fuel the damaging brain inflammation seen in Alzheimer’s disease. They found that a protein called STING becomes chemically altered in...

Scientists discovered that sleep deprivation damages a key brain circuit responsible for social memory, making it harder to recognize familiar individuals. In laboratory studies, caffeine restored communication...

Scientists at Stanford may have uncovered a hidden reason our brains decline with age. Studying the ultra-short-lived turquoise killifish, researchers discovered that the cellular machinery responsible for building...

Cambridge researchers created miniature brain-and-spinal-cord systems in the lab that can send signals and even trigger tiny muscle contractions. They discovered that human neurons gradually lose their ability to...

CBD may be doing far more than just easing pain or anxiety — new research suggests it could help fight Alzheimer’s disease by calming the brain’s runaway immune response. In experiments using Alzheimer’s mice,...
