Figure 2.

Intensity and pleasantness ratings of the four different events of interest. We plotted mean pleasantness, edibility, wanting, and familiarity (rated on a VAS) and intensity, sweetness, saltiness, sourness, and bitterness (rated on a gLMS) ratings (averaged over subjects, ±SEM) against time and session (x-axis). BT, Before training; AT, after training; BS, before scan; AS, after scan. Dark gray bars, Sweet stimuli; light gray bars, tasteless stimuli. Sweet stimuli are perceived to be significantly more intense and sweet (*p < 0.05), and a trend for sweet is perceived to be rated as more edible and pleasant (⁺p < 0.1). Edibility ratings were lower before the sessions than after the sessions (*p < 0.05). There was a significant decrease in wanting of either stimulus before compared with after the scanning session (*p < 0.05).
