a) The average ranking scores by frequency, b) the average ranking scores by channel, and c) the five dominant channels corresponding to the visual (column 1) and auditory (column 2) phoneme task. The channels 22 and 32 are equally ranked. Color corresponds to cortical areas (red: ventral sensorimotor cortex, green: superior temporal gyrus, purple: superior temporal sulcus, yellow: inferior temporal gyrus, light blue: middle temporal gyrus). The frequency resolution is 8 Hz.
