Abstract

We examined the spontaneous activity of single neurons within the nucleus parabrachialis medialis (NPBM; pneumotaxic center) of unanesthetized, unrestrained cats in relation to the respiratory cycle during different sleep-waking states. State-related changes were found in the mean discharge rate of NPBM neurons and in the relationship of their activity to the respiratory cycle. These changes in pneumotaxic center neuronal activity paralleled the variations in respiratory patterns associated with different sleep-waking states. State-related changes in NPBM neuronal activity could partially account for the different respiratory patterns of each sleep-waking state by modulating inspiratory-expiratory phase transitions.
