Figure 4. Results of the psychophysiological interactions (PPI) analysis with a left AI seed.

Figure 4

(A) The dACC demonstrated larger increase in functional connectivity with the left AI in the NoChew conditions (NoChew_Noise > NoChew_NoNoise) than in the Chew conditions (Chew_Noise > Chew_NoNoise). (B) The correlation coefficients between the BOLD signal in the left AI seed and that in the dACC (for detail, see Method: Psychophysiological interaction). (C) The BOLD signal extracted from the dACC in (A). Error bars indicate the variance of the correlation coefficents (±SEM). * p<0.05; (*) 0.05<p<0.07.
