Scientists find link in humans between nerve cell production, memory

Por • 9 sep, 2010 • Category: Ciencia y tecnología

Production of new nerve cells in the human brain is linked to learning and memory, according to a new study from the University of Florida. The research is the first to show such a link in humans. The findings, published online and in an upcoming print issue of the journal Brain, provide clues about processes involved in age- and health-related memory loss and reveal potential cellular targets for drug therapy.
