Neuroscientists get at the roots of pessimism

Researchers at MIT found that stimulating the caudate nucleus, a brain region linked to emotional decision-making, induces animals to make more negative decisions. The study suggests that this type of pessimistic thinking could influence approach-avoidance decision-making and may be related to depression and anxiety.
