Abstract
Social deprivation of rhesus monkeys in infancy results in increased sensitivity to psychotic-like behavioral effects of low doses of d-amphetamine given 2–3 years later. These behavioral effects are associated with increased levels of CSF norepinephrine. These data suggest that social developmental factors could be partially responsible for variation in neurochemical responses and long-lasting differential sensitivity of primates to the psychosis-inducing effects of d-amphetamine.
