title: Respiratory neurons of the pneumotaxic center during sleep and wakefulness.
abstract: Extracellular recordings were made from respiratory related units (RRUs) in the pneumotaxic center (PNC) of unanesthetized cats across states of consciousness: wakefulness, NREM and REM sleep. Contrary to expectations from results in acute preparations, well-modulated respiratory activity was detected in chronic animals with vagi intact. Pontine RRU activity decreased during sleep in 75% of the cells studied. The greatest reduction occurred during REM sleep.
