Science Update
Just as traffic signals enable safe traversing of the roadways, so too does the brain’s machinery for learning and memory rely on its own stop-and-go signals. An NIMH grantee has traced a human learning disability to an imbalance in signals that increase and decrease neural activity – and demonstrated a way to correct it. The study in mice, published in the October 31, 2008 issue of the journal Cell, advances scientific understanding of how memory works. - NIMH, U.S. Army Sign MOA to Conduct Groundbreaking Suicide Research

Science Update
In the first study of its kind, researchers have pinpointed four genes likely associated with risk for the most common, late-onset form of Alzheimer’s disease, including a very strong candidate on chromosome 14. NIMH grantee Rudolph Tanzi, Ph.D., of Massachusetts General Hospital and Harvard University, and colleagues report on their findings in the November issue of the American Journal of Human Genetics. - Cells May Provide Target for New Anxiety Medications

•
Science Update
For the first time, scientists have mapped groups of genes that turn on together in the human brain, revealing a kind of Rosetta Stone of its molecular organization. These never-before-seen patterns of co-expressed genes hold promise for implicating genetic mechanisms conferring risk for illness through “guilt by association,” say the researchers. - New Grant Aims to Reduce Rate of College Suicide by Helping Students Better Adjust
