MEG Data from Study 2: Right Second Digit Tactile Stimulation. (A) Butterfly plot of all 275 MEG sensors overlaid from −180 ms to 145 ms post-stimulus onset, with aqua lines representing the same 25 ms (x-axis) and 10 fT (y-axis) increments as in Figure 1 (see scale in bottom left). The black line marks 0 ms (stimulus onset), the red line marks the peak of the earliest and strongest response at 16 ms, and the blue line indicates the peak of the later response at 96 ms. (B) Flux map reflecting field strength gradients across the sensor array at 16 ms. The orientation of the map and the meaning of red and blue are consistent with Figure 1. (C) Same as (B) except map displays field strength across the array at 96 ms (peak latency for later response). Notice the orientation of the current source has again rotated, but that the center of the zero crossing remains the same.
