Description

The circuit both drives sleep through lateral hypothalamus and inhibits CRF release in paraventricular hypothalamus, but the molecular mechanisms enabling this dual function are not explained. This coordination mechanism could inform treatments targeting both sleep and stress hormone dysregulation.
