Scientists at The Scripps Research Institute (TSRI) have decoded an important molecular signal that guides the development of a key region of the brain known as the neocortex. The largest and most recently evolved region of the brain, the neocortex is particularly well developed in humans and is responsible for sensory processing, long-term memory, reasoning, complex muscle actions, consciousness and other functions. "The mammalian neocortex has a distinctive structure featuring six layers...

By shedding new light on how cells migrate in the developing brain, researchers at Fred Hutchinson Cancer Research Center also may have found a new mechanism by which other types of cells, including cancer cells, travel within the body. The findings by Jonathan Cooper, Ph.D., member and director of the Hutchinson Center's Basic Sciences Division, and Yves Jossin, Ph.D., a research fellow in Cooper's laboratory, published online April 24 in Nature Neuroscience, could lead to a better...

By Jeremy Lovell LONDON -- They could be the missing links of human genetic evolution -- areas of human DNA that changed dramatically after the evolutionary division from chimpanzees, though they had remained almost unchanged for millennia before. Scientists from the United States, Belgium and France identified 49 "human accelerated regions" (HARs) showing a lot of genetic activity. In the most active, identified as HAR1, they found 18 out of the 118 nucleotides had changed since evolutionary...


Word of the Day
