Chronic stress impairs spatial memory and motivation for reward without disrupting motor ability and motivation to explore.

abstract：:Rhesus monkeys were trained to learn a large series of visuomotor conditional associations, each involving the arbitrary coupling of a visual stimulus with 1 of 3 potentially correct forelimb movements. The monkeys then received bilateral aspiration lesions of either the amygdala plus subjacent cortex or the hippocamp...
