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