In addition to increased variability, the P1 peak in the participants with ASD occurred significantly sooner than in the control group. This finding, from these data, was reported previously (Milne et al., 2009), so will not be dwelt on here. Nevertheless, reduced latency to peak is commensurate with the suggestion of local hyper-connectivity in ASD which has been predicted by some to lead to increased cortical noise (see for example, Belmonte et al., 2004).
