Sponsored by the Department of African American Studies, the W.E.B. Du Bois Institute, and the Committee on African Studies, the panel assembled a variety of perspectives on the Haitian crisis from writers, including Haitian-born poet Patrick Sylvain, and doctors like Mary Louis Jean Baptiste, a Haitian-American mental health expert...
Popular wisdom once held that a mind at rest was like an engine idling - not much going on under the hood. To glean insights into how the brain worked, scientists would study only volunteers in action, measuring their physiological or biochemical responses as they completed specific mental tasks. But more recently, thanks in large part to the proliferation of functional magnetic resonance imaging (fMRI), which precisely maps brain activity based on changes in blood-oxygen levels, neuroscientists have found that important activity in the brain - related in particular to memory and learning - may occur when it is at rest...
...question that has plagued researchers is whether the observed increase in brain activity that occurs after the completion of a mental task is just a ripple or echo effect, rather than a distinct event that helps solidify memories. Harvard researcher Dale Stevens believes he has more or less ruled out the former possibility by showing that even tasks that produce similar levels of neural activity while they are being performed, such as recognizing a face versus a landscape, result in different levels of activity after each task is completed. In Stevens' studies, brain activity remained high after people viewed landscapes...
Though some former players have been making their cases for years, the NFL has until recently downplayed any link between football head trauma and cognitive decline. In 2009, after a study sponsored by the league showed evidence that retired players had long-term mental trauma, and after more damaged players came forward, Congress stepped in. At one hearing, Representative Linda Sanchez, a Democrat from California, compared the NFL's stance on concussions to tobacco companies' denial that smoking causes lung cancer. Others have taken up the players' cause, like Gay Culverhouse, the terminally ill former president of the Tampa...
