Example of a brief occurrence of a seemingly common rhythm in lingual EMGs and diaphragm during REMS. During the second half of this 9 s-long record from the sites labeled in Fig. 2 as H63, the diaphragm and both the proximal (Prox.) and intermediate (Interm.) lingual EMGs have periods of rhythmic activity at rates that are considerably faster than typical respiratory rates during REMS (cf., integrated diaphragm EMG in the first half of the record). However, a close examination of these activities reveals variable phase relationships between the bursts in the diaphragm and lingual muscles. Such fast rhythms with variable phases of diaphragmatic and lingual activations frequently occur during REMS, suggesting that lingual and diaphragmatic EMGs are driven by different central pattern generators.
