Abstract. It is established that the brain monoaminergic systems are among the main targets of several dependence-inducing drugs, including nicotine. In the present study extracellular electrophysiological recordings were performed to investigate the effects of nicotine on dorsal raphe 5-HT neurones. Nicotine, administered systemically (50400g/kg, i.v.) in chloral hydrate-anaesthetised rats, induced...
Abstract. The effects of the nicotinic acetylcholine receptor (nAChR) agonist epibatidine on the extracellular concentrations of dopamine (DA) and its metabolites 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) in the dorsal (caudate-putamen) and the ventral striatum (nucleus accumbens) of freely-moving male Wistar rats were studied by in vivo microdialysis. In the dorsal striatum,...
