Psychophysiological interaction results. Regression of activity in anterior insula (AI) on the activity in the seed regions IPS and VS when the oral stimulus was unexpected (light gray circles and solid gray line) versus expected (dark gray triangles and dashed dark line). Each observation corresponds to the time series interaction with that condition. The section by the x-axis shows the location of the seed region, and the section by the y-axis shows the neural response in anterior insula that was significantly associated with a stronger connectivity under unexpected versus expected with the seed region. The color bar depicts T values. au, Arbitrary units.
