ANN ARBOR, Mich. — University of Michigan Health System researchers have found new evidence that our genes help determine our susceptibility to depression.

Their findings, published online today in the Archives of General Psychiatry, challenge a 2009 study that called the genetic link into question and add new support to earlier research hailed as a medical breakthrough.

New York, NY (January 3, 2010) --- Parent education programs delivered through pediatric primary care offices increased parent-child play and reading activities critical for child development and school readiness during infancy in at-risk families, according to two concurrent reports in the January issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.

The use of general anesthesia is a routine part of surgical operations at hospitals and medical facilities around the world, but the precise biological mechanisms that underlie anesthetic drugs' effects on the brain and the body are only beginning to be understood. A review article in the December 30 New England Journal of Medicine brings together for the first time information from a range of disciplines, including neuroscience and sleep medicine, to lay the groundwork for more comprehensive investigations of processes underlying general anesthesia.

Scientists have discovered that the amygdala, a small almond shaped structure deep within the temporal lobe, is important to a rich and varied social life among humans. The finding was published this week in a new study in Nature Neuroscience and is similar to previous findings in other primate species, which compared the size and complexity of social groups across those species.
