An example of spatial integration obtained from a right-handed subject. The waveforms show the time courses of the averaged magnetic field responses recorded from 275 sensors under the different conditions. The left and right columns show contralateral sensor response waveforms for LD2 and RD2 stimulation, respectively. a and f: D2 stimulation alone at low rate (condition 1 in Figure 6; mean ISI: 2s); b and g: D2 stimulation alone at high rate (condition 2 in Figure 6; ISI: 0.33s); c and h: D2 deviant plus D3 standard stimulation (condition 3 in Figure 6; ISI: 0.33s); d and i: D2 deviant plus D4 standard stimulation (condition 4 in Figure 6; ISI: 0.33s); e and j: D2 deviant plus opposite D2 standard stimulation (condition 5 in Figure 6; ISI: 0.33s).
