Figure 3.

MEG source waveforms in the left and right hemisphere auditory cortex in response to auditory and visual stimulation, shown separately for the noise/checkerboard and letter experiments. The source waveforms were averaged over subjects. The locations of the functional ROIs morphed to common anatomical space (“fsaverage” from FreeSurfer) are shown in the middle; the color bar indicates how many subjects’ individual ROIs overlapped at each cortical location. The black lines illustrate the Heschl's gyrus (anterior), Heschl's sulcus (middle), and part of planum temporale (posterior).
