Summary

Besides the master clock located in the suprachiasmatic nucleus (SCN) of the brain, additional clocks are distributed across the central nervous system and the body. The role of these ‘secondary’ clocks remains unclear. A new study shows that the lack of an internal clock in histamine neurons profoundly perturbs sleep.
