Neural Substrates Of Controlled And Automatic Processes Involved In Empathy For Pain
Seeing others in pain can automatically engage the brain"s empathy systems even if we are not paying attention, according to new research from Mount Sinai School of Medicine presented at the Annual Meeting of the Organization for Human Brain Mapping. The investigators showed people images of hands and feet in painful or non-painful situations while scanning the brain using magnetic resonance imaging. Under some conditions the subjects paid attention to whether the situation was painful, while in other conditions they paid attention to other aspects of the images. The results showed that a brain area called the insula responded to pain even if the subject was not paying attention to pain, while another area called the anterior cingulate cortex was important for the voluntary control of empathy for pain. The research provides a better understanding of how the social brain responds to others" pain.

Washington Post Examines Health Toll Of Congo Conflict

The Washington Post examines the devastating toll the conflict in the Congo has had on the health of the country"s displaced civilians, as told through the death of a 36-year-old farmer, who succumbed to typhoid fever far away from the home he abandoned. The newspaper writes, "By some estimates, at least 5 million Congolese have died in more than a decade of conflict touched off by the 1994 genocide in neighboring Rwanda, which sent a flood of militiamen across the border into mineral-rich eastern Congo." While the "conflict has surged, receded and changed over time ò€¦ for the most part ò€¦ people in eastern Congo have not died in a blaze of bullets or in large-scale massacres. More often, the conflict has set off a chain reaction of less spectacular consequences that begins with fleeing through an unforgiving jungle and ends with a death." There, displaced people face injury, lack of food or clean water as well as diseases like malaria, diarrhea, and measles. The Washington Post writes that the conflict has "scattered" whole villages "across hundreds of miles," and "has overwhelmed already-dysfunctional government hospitals and left roads rutted and overgrown." "At the moment, the conflict in eastern Congo is surging once again," the Washington Post writes, adding, "Since January, at least half a million people have fled a U.N.-backed Congolese army operation targeting Rwandan rebels" - a topic Secretary of State Hillary Rodham Clinton is expected to discuss in a visit to Congo this month" (McCrummen, 8/2). A separate Washington Post article examines the of "frequently cited death toll" data from eastern Congo and looks at some of the causes of death (McCrummen [2], 8/2).
