Changes in dopamine levels linked to infant learning patterns

27. October 2009 01:59

When do you first leave the nest? Early in development infants of many species experience important transitions-such as learning when to leave the protective presence of their mother to start exploring the wider world. Neuroscientists have now pinpointed molecular events occurring in the brain during that turning point. [More]

Short stressful events may improve working memory

23. July 2009 21:25

Experiencing chronic stress day after day can produce wear and tear on the body physically and mentally, and can have a detrimental effect on learning and emotion. However, acute stress -- a short stressful incident -- may enhance learning and memory. [More]

Poor sleep disturbs neuroendocrine control of appetite

22. April 2009 13:33

Laboratory and epidemiological studies continue to show that sleep curtailment and/or decreased sleep quality can disturb neuroendocrine control of appetite, leading to overeating, and can decrease insulin and/or increase insulin resistance, both steps on the road to Type 2 diabetes. [More]

Exercise increases brain growth factor and receptors, prevents stem cell drop in middle age

18. November 2008 03:55

A new study confirms that exercise can reverse the age-related decline in the production of neural stem cells in the hippocampus of the mouse brain, and suggests that this happens because exercise restores a brain chemical which promotes the production and maturation of new stem cells. [More]
