since the firing rate of both a10 ( ventral tegmental area ) and a9 ( substantia nigra ) dopamine neurons has previously been shown to be increased by phencyclidine , these data suggest that phencyclidine results in a differential regulation of presynaptic release of dopamine in mesolimbic/cortical as opposed to nigrostriatal dopaminergic regions .
