Fig. 2.

Example of the ensemble-average of the rectified raw genioglossus EMG and the corresponding mask pressure in one individual subject. The key components used to quantify reflex responses and stimulus characteristics are highlighted, including stimulus onset (vertical line), stimulus magnitude (nadir pressure), baseline genioglossus EMG (horizontal line), reflex excitation onset, excitation peak, suppression onset/excitation cessation, suppression nadir, and suppression cessation. Refer to the text for further details.
