Abstract

The circadian pacemaker in mammals is located in the suprachiasmatic nuclei (SCN). Recent evidence indicates that the related peptides VIP and PACAP are (1) differentially present in SCN afferents (from the retina), intraSCN connections and extraSCN efferents and (2) differentially capable of phase-shifting the clock when administered at specific phases of the cycle (VIP can mimic the effects of a light pulse and PACAP those of a dark pulse). We will adopt a multidisciplinary approach involving behaviour, neurophysiology, in situ hybridisation, RT-PCR and transgenic animals to elucidate the distinct roles and sites of action of these peptides in circadian processes and the mechanisms underlying the gating of the phase-specific responses.
