VEP waveforms in children with 16p11.2 deletions and duplications. a Averaged waveforms are displayed for each individual (thin traces) and each group (thick traces) for controls (black), deletion carriers (blue), and duplication carriers (green). The x-axis plots time in milliseconds, where −100 to 0 is the baseline period, 0 is the onset of the stimulus, and 0 to 300 is the response to the stimulus. The y-axis plots amplitude in microvolts. b Group average responses are displayed in an overlapping fashion to facilitate comparison between groups. c P1 latency is quantified for each individual. Open circles indicate individuals with a positive diagnosis for ASD. The line indicates the median for each group. d P1 amplitude is quantified for each individual. Open circles indicate individuals with a positive diagnosis for ASD. The line indicates the median for each group. **p < 0.01
