Weba 6-h phase advance of the LD cycle. Nevertheless, induction of c-Fos by light in late night is normal. In all experiments, PACAP-null mice show specific behavioral impairments in response to phase-advancing photic stimuli. These results suggest that PACAP is required for the normal integration of the phase-advancing light signal by the SCN.

WebWithin the ventrolateral SCN, the photic induction of Fos expression occurred in neurons expressing gastrin-releasing peptide (GRP), but not in those containing vasoactive intestinal polypeptide (VIP). This finding suggests that SCN neurons containing GRP may be involved in the transduction of photic signals mediating circadian entrainment. authors WebPhotic Induction and Maintenance of Sleep Many early studies examining the relationship between light and its capacity to induce sleep used short light-dark cycles of various …
WebJul 4, 2024 · Exposure of mice to a 24 h light:dark:light:dark (LDLD) cycle with dimly illuminated nights induces the circadian timing system to program two intervals of activity and two intervals of rest per 24 h cycle and subsequently allows entrainment to a variety of extraordinary light regimens including 30 h LDLD cycles.
