Abstract:
The effects of centrally administered galanin (10 and 20 mcg) on the EEG, somatic behaviour and some autonomic parameters have been studied in unanesthetized rabbits. In this species the peptide induced a dose related increase in electrocortical power spectrum density and behavioural sedation. Autonomic changes, consisting in moderate hyperthermia and bradypnea, were seen only after the highest dose of the peptide. These data support a central action of the peptide and suggest a role for galanin as sedative neuropeptide.
