Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

First-of-its-kind analysis published in the Feb. 8 PNAS supports the concept of a basic wiring diagram for all eukaryotes. Researchers in California, Israel, and Germany have compared three distantly related species ?baker's yeast, a worm, and the fruit fly ?and reported that protein "wiring" connections in one species are often conserved in all three. This first-of-its-kind analysis of t...

Deep sleep short-circuits brain's grid of connectivity

In the human brain, cells talk to one another through the routine exchange of electrical signals. But when people fall into a deep sleep, the higher regions of the brain - regions that during waking hours are a bustling grid of neural dialogue - apparently lose their ability to communicate effectively, causing consciousness to fade. Writing today (Sept. 30) in the journal Science, a team o...

Aggression-related gene weakens brain's impulse control circuits

A version of a gene previously linked to impulsive violence appears to weaken brain circuits that regulate impulses, emotional memory and thinking in humans, researchers at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) have found. Brain scans revealed that people with this version ?especially males ?tended to have relatively smaller emotion-related brain str...

Hap1 protein links circulating insulin to brain circuits that regulate feeding behavior in mice

Researchers have discovered how the protein Hap1, which is abundant in the brain's hypothalamus, serves as the link between circulating insulin in the blood and the neural circuitry that controls feeding behavior in mice. Illumination of the neural pathway used by hormones to regulate appetite and eating behavior could eventually provide new drug targets for treating eating disorders and o...

The brain, traffic and nano-circuits -- e-Science takes on major challenges

Research into three major scientific and technological challenges is to receive a major boost from the application of e-Science and grid computing. The challenges are, understanding the brain, mapping the detailed environmental impact of traffic and designing future generation nano-scale electronic circuits. The Engineering and Physical Sciences Research Council (EPSRC) and other funding p...
