Respiratory-related activity in hypoglossal neurons across sleep-waking states in cats.
Activity of behaviorally identified neurons in the hypoglossal nuclei supplying the genioglossal muscles was assessed in intact, unanesthetized cats across sleep-wake states. Nineteen of 37 recorded cells discharged on a breath-by-breath or tonic basis with the respiratory cycle in at least one state. Most respiratory-related cells discharged more slowly during quiet sleep, whereas rates during rapid eye movement sleep were similar to those of waking.
