Where in the brain decisions are made
While neurobiologists have long suspected that certain regions of the brain are specifically involved in making decisions, the challenge has been to develop rigorous laboratory behavioral experiments that could pinpoint those areas. Now, Paul Glimcher and colleague Michae...UCSD biologists discover chemical important in guiding visual system development
University of California, San Diego neurobiologists have discovered a chemical responsible for the bursts of electrical activity in the brain that guide the development of the visual system, a finding that may bring rewiring of damaged visual circuits closer to reality. The scientists, who presente...How the brain is wired for faces
...nd to the sight of a face almost from birth. While neurobiologists have known that a particular area of the brain, called the fusiform face area (FFA), lights up with activity when we see a face--and even that the FFA is necessary for us to recognize faces--there is controversy over what kind of processing the area ...Important brain finding results from boy's rare, fatal disease
...h in the hospital, a team of neuropathologists and neurobiologists worked through the night to isolate some of Nathan's brain cells, which were then grown and studied in the laboratory.

Duke University Medical Center neurobiologists have pinpointed circuitry in the brains of monkeys that assesses the level of risk in a given action. Their findings -- gained from experiments in which they gave the monkeys a chance to gamble to receive juice rewards -- could give insights into why...Flip-flopped chromosome reveals a first clue to Tourette syndrome

In particular, they found one gene expressed in the brain near the chromosomal break point. They compared the gene to a wider...Research: removal of dominant rivals causes male cichlid fish to undergo remarkable transformation
