Fig. (3) Statistical source maps of differences in t values (p<0.05) at 50-100 Hz. A: In the sagittal image in the left hemisphere, ERD in males was significantly increased in the cACC region at 125 ms, and in the inferior temporal regions at 625 ms. B: In the sagittal image in the right hemisphere, ERD in males was significantly increased in the cACC and lingual regions at 125 ms. (P: posterior, A: anterior, ERD: event-related desynchronization; ERS: event-related synchronization; cACC: caudal anterior cingulate cortex).
