Dizocilpine blocks the effects of delta sleep-inducing peptide-induced suppression of c-fos gene expression in the paraventricular nucleus of the hypothalamus in rats

Abstract

The characteristics of the actions of the non-competitive blocker of NMDA receptors dizocilpine on the expression of the early c-fos gene in the paraventricular nuclei of the hypothalamus were studied in rats with different predicted susceptibilities to emotional stress in conditions of treatment with delta sleep-inducing peptide. The results showed that prior treatment with dizocilpine blocked reductions in c-fos expression induced by delta sleep peptide.
