Paired stimulation paradigm using auditory and somatosensory change-related cortical responses.

<p>Data from a representative subject are presented. Shown is the stimulation paradigm, superimposed MEG waveforms from all 204 sensors, and source strength waveforms for each cortical activity in the auditory (A) and somatosensory (B) experiments. T, sensory threshold. Arrowheads show peaks of source activity used for amplitude measurements.
