Neural response to expected versus unexpected events. Sagittal sections show neural response to expected versus unexpected oral stimuli ([ExpSwt + ExpTless] − [UnSwt + UnTless]) in bilateral fusiform gyrus. The bar graphs show (on the y-axis) the percentage signal change for the expected (dark gray bars) and unexpected (light gray bars) events (±SEM), averaged over subjects. Stimuli are shown on the x-axis. The response was taken from the voxel that responded maximally within the significant cluster, as identified in the SPM analysis. The color bar depicts T values.
