Resistance to stress: multiple neurochemical, behavioral and genetic factors.

Stressful events induce a variety of neurochemical alterations which are believed to subserve behavioral disturbances. Although stressor-induced behavioral and neurochemical alterations have been reliably observed, appreciable interindividual differences exist in this respect. It is suggested that genetic analyses may be ideal in assessing the relationship between the neurochemical and behavioral sequelae of acute stressors, as well as the processes subserving adaptation to chronic stressors.
