UCI Study Finds Drug Prevents Key Age-Related Brain Change In Rats
As brain cells age they lose the fibers that receive neural impulses, a change that may underlie cognitive decline. Researchers at the University of California, Irvine recently found a way to reverse this process in rats. The study was published February 3 in The Journal of Neuroscience. Researchers caution that more studies are needed, but the findings shed light on the mechanisms of cognitive ... Read News
