Abstract
Choline acetyltransferase (ChAT) activity was measured in discrete are as of rat brain after chronic, unlimited access to self-administration of cocaine. Mean activity of ChAT was reduced by approximately 30% in the nucleus accumbens, both on the last day of cocaine access and aft er 3 weeks cocaine withdrawal. These data suggest that chronic cocaine exposure might inhibit nucleus accumbens cholinergic neurones which c ould underlie some of the behavioral effects of cocaine.
