Summary
AI-generated from the abstractDesipramine both potentiates and antagonizes the responses of single cortical neurones to mescaline. The antagonism may stem from desipramine's α-adrenolytic action, while the potentiation is unlikely due to uptake blocking because desipramine does not block mescaline uptake in the cerebral cortex. The potentiation may instead result from a post-synaptic action of desipramine.

Abstract
The effect of desipramine on responses of single cortical neurones to mescaline was studied by the microelectrophoretic technique. Both potentiation and antagonism of responses to mescaline by desipramine were observed. The antagonism may be related to the α‐adrenolytic action of desipramine. The potentiation is unlikely to reflect the uptake blocking action of desipramine, since desipramine does not block the uptake of mescaline in the cerebral cortex. It is suggested that the potentiation may be due to a post‐synaptic action of desipramine.
