The dopamine innervation of the prefrontal cortex can be differentiated from other telencephalic dopamine projection fields by its sensitivity to stress. The stress-induced activation of the mesoprefrontal cortical dopamine system can be blocked by pretreatment with benzodiazepines. A group of neuroactive steroids that modulate GABA-induced chloride flux through means distinct from that of the benzodiazepines has recently been identified. Intraventricular administration of the neuroactive steroid 3 alpha,21-dihydroxy-5 alpha-pregnane-20-one resulted in a dose-dependent decrease in dopamine metabolites in the prefrontal cortex, but not in mesolimbic or striatal sites; sedative effects were not observed. Moreover, the neuroactive steroid selectively attenuated the stress-induced activation of the mesoprefrontal cortical dopamine system. These data suggest that neuroactive steroids may function as endogenous anxiolytic agents.
