Self-administration of intravenous amphetamine: effect of nucleus accumbens CCKB receptor activation on fixed-ratio responding

Abstract

Rationale: The mesolimbic dopamine (DA) system is implicated in psychostimulant drug self-administration. The neuropeptide cholecystokinin (CCK) is co-localised with DA and inhibits nucleus accumbens (NAcc) DAergic neurotransmission via CCKB receptors. Objectives: The present experiment was designed to examine the effects of intra-NAcc CCKB receptor… (More)
