the similarity of this behavior to that seen after systemic administration to experimental animals of exogenous neuroleptics suggests that a disturbance in the bioavailability of this neuropeptide to receptor sites in brain-perhaps due to lack of enzymatic cleavage from the circulating parent hormone , beta-lipotropin -- may be an etiological factor in those psychopathological states for which the exogenous neuroleptics exert an ameliorative influence .
