Abstract
Vasopressin release increases late in sleep. Suprachiasmatic clock neurons modulate osmosensory synapses onto vasopressin neurons to facilitate osmoregulated vasopressin release, reports a study in this issue. This explains the increased late-night vasopressin release, and such facilitation prevents dehydration during sleep.
