Study spotlights uniqueness of human brain

...sually large brains compared to apes, our closest primate relatives. Butuntil now, evidence of differences in the internal structure of human andprimate brains has been lacking. In a groundbreaking study published today by the National Academy of Sciences, ateam of scientists led by Dr. Todd Preuss of the U...

Duke team seeks novel vaccine strategy for HIV

... "Our role in this project is to use our non-human primate models toexplore novel vaccine strategies for preventing HIV infection," Letvin said. "Any successes in these monkey studies should rapidly translate into success inhumans. The power of the models we have developed is enormous. "The virus (S...

MCG researchers find clues in process that enables working memory

...rotein which was identified by researchers in the primate brain may help explain why schizophrenics typically lack normal working memory yet have normal dopamine D1 receptors. "Anything that regulates how the dopamine D1 receptor works could be a candidate for a gene that is defective in schizophrenia," Dr...

...rongest marker we've found so far in the non-human primate that predicts alcohol consumption." He added that, "to the extent that this can be generalized to humans, we may have identified a biological predictor of future alcohol problems." Higley said the second implication is that "early-rearing experienc...

'Bird brains' take heart-our feathered friends are no slouch at cognition
