Steven A. Brown and the synchronization of circadian rhythms by body temperature cycles

open access: yesEuropean Journal of Neuroscience, Volume 60, Issue 2, Page 3891-3900, July 2024.
The master pacemaker in the suprachiasmatic nucleus (SCN) and ambient temperature cycles determine the phase and amplitude of body temperature oscillations. The latter, in conjunction with feeding–fasting rhythms and blood‐borne signals, participate in the synchronization of circadian clocks in peripheral organs.
