•Dyscoordination of dilator muscles during sleep contributes to pharyngeal collapse.•We found a sleep-dependent shift in peri-pharyngeal muscles power spectrum.•This finding suggests a state-dependent alteration in dilators motor unit activation.•We speculate that this change may lessen dilator musc...
