The cyclic AMP response to catecholamines in rat cortical slices is mediated by a beta adrenergic receptor which is coupled to adenylate cyclase and an alpha adrenergic receptor which potentiates the response to beta receptor stimulation. The present studies examined the effects of repeated restraint stress, adrenocorticotropin or desmethylimipramine(More)
The cyclic AMP response to catecholamines in the rat cerebral cortex is mediated by both beta- and alpha-adrenoceptors. The beta-receptors cause a direct activation of adenylate cyclase whereas the alpha alpha-receptors play a modulatory role and act by potentiating the response to beta stimulation. The present study investigated whether the functions of(More)
Amphetamine locomotor sensitization is an animal model for the study of addiction and schizophrenia. The antipsychotic clozapine blocks the hyperlocomotion induced by an acute injection of amphetamine, but its effect on locomotor sensitization after repeated amphetamine administration remains unknown. In the present study we investigate the effect of(More)
The cyclic adenosine monophosphate response to catecholamines in the rat brain is mediated by beta-adrenergic receptors which activate adenylate cyclase and by alpha-adrenergic receptors which potentiate the response to beta-stimulation. We have found that the alpha-potentiation effect in the olfactory bulb is 2-3X greater than in other forebrain areas.(More)
