Excerpt: Functional MRI scans have revealed a "biologically embedded" basis for altruistic behavior, with several characteristic regions of the brain being activated when players of a game called "Prisoner's Dilemma" decide to trust each other and cooperate, rather than betray each other for immediate gain, say researchers from Emory University. They report on their study in the July 18 issue of the journal Neuron, published by Cell Press. -- "Erik Reuter" <[EMAIL PROTECTED]> http://www.erikreuter.net/
