The effects of serotonin injections into the locus coeruleus on ponto geniculo occipital (PGO) waves and cortical EEG pattern in cats.

Reserpine injected iv at 0-8--1-0 mg/kg doses induced continuous ponto-geniculo-occipital (PGO-like) waves in immobilized cats. Both 5-HT and quipazine injected into the locus coeruleus decreased the frequency of reserpine-induced PGO waves and increased cortical synchronization. Suppression of PGO activity persisted for 15--30 min whilst synchronizing effects lasted much longer. Methysergide increased the frequency of PGO activity but caused no clear changes in the EEG pattern.
