Fast cyclic voltammetry at carbon fibre microelectrodes was used to monitor stimulated release of electroactive species simultaneously in both caudate and nucleus accumbens. The released species was identified as dopamine in both nuclei on the basis of anatomical, electrochemical and pharmacological criteria. Dopamine release in the nucleus accumbens was consistently evoked at more ventromedial stimulation sites than for caudate. In both nuclei, release was reduced or abolished by alpha-methyl-p-tyrosine and Ro 4-1284. Pargyline, cocaine and GBR 12909 potentiated release while desipramine had no effect. In conjunction with the electrochemical data, the results indicate that dopamine is the sole species detected in caudate and accumbens following stimulation of the median forebrain bundle.

D003042	Cocaine	An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.

D003342	Corpus Striatum	Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.

D003891	Desipramine	A tricyclic dibenzazepine compound that potentiates neurotransmission. Desipramine selectively blocks reuptake of norepinephrine from the neural synapse, and also appears to impair serotonin transport. This compound also possesses minor anticholinergic activity, through its affinity to muscarinic receptors.
