Figure 3: MRCPs differ as a function of participant group. (A) Group average topography across all 168 participants illustrating the frontal and left centro-partietal dipolar foci of the MRCP. (B) Average waveforms from frontal electrode Fz plotted for TD participants (blue) and ASD participants (red). Shaded regions surrounding waveforms indicate standard error of the mean. (C) Fronto-central electrode FCz. (D) Left parietal electrode P3. (E) Right parietal electrode P6. (F) Statistical cluster plot illustrating scalp locations and time course of statistical differences between ASD and TD participants. (G) Average scalp topography for TD (left) and ASD (right) participants between 250 to 200 ms prior to the button press within the period of the late BP. (H) 150 to 100 ms prior to the button press during the late BP. (I) 0 to 50 ms after the button press, encompassing the MP component.
