Fig. 3From: The electroretinogram b-wave amplitude: a differential physiological measure for Attention Deficit Hyperactivity Disorder and Autism Spectrum DisorderComparison of the representative light-adapted ERG waveforms of one individual from each group. The ERG waveforms of each ADHD, control and ASD individual at the nine randomised flash strengths are displayed on the left panel. The right panel enlarges the image of the representative ERG waveforms produced by the 1.204 log phot cd.s.m−2 flash strength, which showed the most significant differences amongst these individuals. The b-wave amplitudes of ADHD are all distinctively higher than both ASD and control individuals at all light strengths. The b-wave amplitudes of ASD are lower than the controls from 0.398 to 1.204 log phot cd.s.m–2Back to article page
