IHTT was calculated for each of the 4 electrode pairs for both P1 and N1 by subtracting the latency of the component peak measured at the electrode contralateral to the visual stimulus from the latency of the component peak measured at the electrode ipsilateral to the stimulus. Linear regression was used to investigate whether it was possible to predict a participant’s IHTT at each of the 4 electrode pairs (i.e., the response variable) on the basis of a linear combination of the FA and Mode of their visual corpus fibers (i.e., the predictor variables). The conservative Bonferroni correction for multiple comparisons was used to control for alpha inflation. Given the 4 electrode pairs and 2 ERP components, alpha was set to 0.05/8 = 0.00625.
