Visual P100. Average waveform (O1, O2) and topographies illustrating the visual P100 component at the bimodal and visual conditions, for controls and ASD. The dashed box highlights the amplitude increase during the bimodal condition compared to the visual, and the speeded latency of the component which is nearly double in controls than the ASD group. The Y-axis of the waveform represents activity in µV and the X-axis time in ms. The colour bar represents the range of activity in µV for interpretation of the topographical maps.
