Grand mean z-scores converted from the time series of oxyHb concentration to sweet (A) and bitter (B) stimulations. The red line represents the mean change in oxyHb (n = 15) and the vertical small line represents the standard error (SE). The vertical bars at 20 s and 50 s represent the onset of stimulation and swallowing, respectively.
