    Abstract

    The antidepressants, mianserin (MIA) and fluoxetine (FLU), were examined to see if they could induce regeneration of catecholaminergic axons in the rat cerebral cortex. MIA, which has a small or no effect in noradrenaline (NA) reuptake but may enhance release by blocking presynaptic inhibition mediated by alpha 2-adrenoceptors, induced regeneration of catecholamine fibers. In contrast, FLU, a potent reuptake blocker of serotonin was ineffective. This finding suggests that the antidepressant-induced regeneration of cortical catecholamine fibers is associated, at least in part, with enhanced noradrenergic transmission.
