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

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.
