New electrophysiological approaches to the suprachiasmatic circadian pacemaker.

Suprachiasmatic nucleus contains the main circadian pacemaker for mammals rhythmical behavior and physiology. In this paper we revise recent experimental advances on electrophysiological studies to suprachiasmatic circadian pacemaker in rodents. Our growing understanding of the electrophysiology of this nucleus will help to elucidate the clock organization and its input and output mechanisms.
