Neurobiology: The heart in the head.

The article relates a study on neurobiology, which investigates correlated brain activity in the efficiency and fairness of decision making. It mentions that Steven Quartz and colleagues of the California Institute of Technology in Pasadena, California, using functional magnetic resonance imaging, found that more efficient decisions correlated with more activity in a brain region called the putamen, whereas decisions that emphasized fairness correlated with more activity in the insula, which is involved with emotional processing.
