Time course of each source activity obtained by source modeling. Source modeling was applied to the waveform of the 2 Hz condition and two difference waveforms (0.5 Hz-2 Hz and 0.1 Hz-2 Hz). Traces show temporal profiles of source strength. Bars in the schematic drawings of the source location and orientation indicate directions of the upward deflection of the waveform. ACC, anterior cingulate cortex; MFG, middle frontal gyrus; Hip, hippocampal region; OP, opercular area; PT, planum temporale; S1, primary somatosensory cortex; STG, superior temporal gyrus.
