FIGURE 2.

Multi‐dipole analysis. A representative participant's data after undergoing left tactile stimulation. (a) Superimposed magnetoencephalography waveforms, recorded using 204 gradiometers with a bandpass filter of 1–100 and 1–30 Hz and source strength waveforms of dipoles in early SI, middle SI, late SI, and cSII. Each waveform's measured peak‐to‐peak amplitudes are indicated by arrowheads. (b) Dipole locations and orientations of each cortical source. SI, the primary somatosensory cortex; cSII, the secondary somatosensory cortex contralateral to the stimulated side
