title: [Participation of 5-HT 1A receptors in the decrease by serotonin of activation of locus coeruleus neurons by glutamate].
abstract: The serotonin-induced decrease of glutamate-evoked activation of noradrenergic locus coeruleus neurons is mimicked by agonists of 5-HT 1 and 1A but not by 5-HT 1B or by 5-HT 2 agonists. Moreover, this effect is reversed by a broad-spectrum 5-HT antagonist but not by a 5-HT 2 antagonist, indicating that this effect is mediated primarily through 5-HT 1A receptors.
