*UCLA-launched partnership identifies genes that boost or lessen risk of brain atrophy, mental illness, Alzheimer’s disease*

In the world’s largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain’s resistance to a variety of mental illnesses and Alzheimer’s disease.

Published April 15 in the advance online edition of the journal Nature Genetics, the study also uncovers new genes that may explain individual differences in brain size and intelligence. (more…)

Experienced meditators seem to be able switch off areas of the brain associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia, according to a new brain imaging study by Yale researchers.

Meditation’s ability to help people stay focused on the moment has been associated with increased happiness levels, said Judson A. Brewer, assistant professor of psychiatry and lead author of the study published the week of Nov. 21 in the Proceedings of the National Academy of Sciences. Understanding how meditation works will aid investigation into a host of diseases, he said. (more…)
