Audiogenic seizures in rats: relation to noradrenergic neurons of the locus coeruleus.
Bilateral lesions involving the nucleus locus coeruleus produced a substantial decrease in the forebrain noradrenaline concentrations. Lesioned animals showed an increased susceptibility to audiogenic seizures. It is supposed that noradrenergic neurons, belonging to the locus coeruleus, play an inhibitory role in the seizure mechanism.
