The effect of various drugs on the extracellular concentration of dopamine in two terminal dopaminergic areas, the nucleus accumbens septi (a limbic area) and the dorsal caudate nucleus (a subcortical motor area), was studied in freely moving rats by using brain dialysis. Drugs abused by humans (e.g., opiates, ethanol, nicotine, amphetamine, and cocaine) increased extracellular dopamine concentrations in both areas, but especially in the accumbens, and elicited hypermotility at low doses.

Mesocortical and mesolimbic dopamine neurons show clear-cut differences in the reactivity to drugs of abuse and to aversive drugs but are both modulated by a facilitatory serotonergic input mediated by 5HT3 receptors.

There is a growing body of evidence in animals and in humans that chronic use of opiates and psychostimulants increases drug cravi11g and chronic exposure to these drugs leads to similar types of sensitization to their acute locomotor-activating effects.

It is concluded that selective activation of 5‐HT2C receptors can block the stimulatory action of nicotine on central DA function, an effect that might be relevant for the reported antiaddictive properties of RO 60–0175.

It is suggested that mesolimbic DA release in response to cocaine is sensitized more readily in AA than in ANA rats, which would not only render the former more susceptible to alcohol, but to other drugs of abuse, and might explain the previous findings that AA rats are more susceptibility to psychomotor sensitization.

Amphetamine induced vigorous rotational behaviour in rats where the nigrostriatal dopamine system was unilaterally degenerated by an intracerebral injection of 6-hydroxydopamine (6-OH-DA) and evidence was obtained that the amphetamine induced release of DA was dependent upon nerve impulses.
