Previous results from our laboratory have indicated that small intravenous doses of the alpha 2-adrenergic agonist clonidine increase serotonin (5-HT) neurotransmission by attenuating the release of endogenous norepinephrine (NE), as a result of the activation of alpha 2-adrenergic autoreceptor on NE neurons, and that high doses of clonidine decrease 5-HT neurotransmission by directly activating alpha 2-adrenergic heteroreceptors on 5-HT terminals.
