Abstract

Action potentials and slow waves were recorded from the hypoglossal nucleus of rats during licking of water from a drinking tube. Periods of licking and of rhythmic neural activity were usually highly correlated, as were their frequencies. Neural activity sometimes continued after cessation of licking; at other times, it stopped during a short interruption of licking and resumed in rhythm with licking. These observations are consistent with an oscillatory model of the control of licking.
