Figure 1.

Representative control, 16p11.2 deletion, and 16p11.2 duplication auditory response profiles. Artifact-corrected source waveforms to a 1000-Hz tone in the RH for a control (left column, 11.78 y.o.), 16p11.2 deletion carrier (middle column, 9.62 y.o.), and 16p11.2 duplication carrier (right column, 13.98 y.o.). All participants are within 1 SD of the mean population age. Source time courses are in the top row and source-sink distribution in the bottom row (source = red; sink = blue). M100 latency for the 16p11.2 deletion carrier is 152 ms, that for the control is 112 ms, and that for the 16p11.2 duplication carrier is 108 ms. From the visualization, the M100 peak is clearly seen based on the magnetic field deflections and the canonical source-sink distribution; there is more lateralization present in the control and as such, the corresponding LH source-sink distribution is not displayed.
