A new neuroimaging study of war veterans with TBI reveals some interesting insights into brain areas associated with altruism.
There are two war veterans, both with penetrating traumatic brain injury (TBI) caused by a gunshot. One of them tends to donate his own money to societal entities he believes in, and the other one punishes institutions that don’t represent him. The answer for these behavioral differences rely on brain areas, that after being damaged during the Vietnam War are no longer working as they are supposed to. In order to elucidate these mechanisms, neuroscientists investigated altruistic behavior – actions that benefit others – in Vietnam veterans. The study was published in Brain.
