  • Title: Respiratory neurons of the pneumotaxic center during sleep and wakefulness.
    Author: Lydic R, Orem J.
    Journal: Neurosci Lett; 1979 Dec; 15(2-3):187-92. PubMed ID: 231237.
    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.
