Mon, 13 May 2013 11:09:09 EDT

Mice that exercise in running wheels exhibit increased neurogenesis in the brain. Crucial to this process is serotonin signaling. Surprisingly, mice lacking brain serotonin due to a genetic mutation exhibited normal baseline neurogenesis. However, in these serotonin-deficient mice, activity-induced proliferation was impaired, and wheel running did not induce increased generation of new neurons.

Why family conflict affects some children more than others

Wed, 08 May 2013 09:28:28 EDT

New research reveals why some children are badly affected by negative family conflicts while other children survive without significant problems. Researchers found that the way in which children understood the conflicts between their parents had different effects on their emotional and behavioral problems. Where children blamed themselves for the conflicts between their parents, they were more likely to have behavioral problems, such as anti-social behavior. But if their parents' fighting or arguing led to a child feeling threatened, or fearful that the family would split up, the child was more likely to experience emotional problems, such as depression.

Acute stress primes brain for better cognitive and mental performance

Tue, 16 Apr 2013 20:45:45 EDT

Chronic stress is known to cause major health problems, yet acute stress can be good for you. A new study shows why.
