S1Supplemental Data Eye Position Affects Activity in Primary Auditory Cortex of Primates

Supplemental Results and Discussion function of eye position, either when holding sound location con-stant (Table S1 lines H, J, L) or when pooling across the tested sound locations (lines G, I, and K). This analysis was conductedIn the following sections, we provide additional analyses supporting the statistical significance of the effect of eye position on auditory in 78 neurons that were tested at 8 or 9 eye positions. All three demonstrated better-than-chance performance in the pooled condi-cortical neurons. We then consider several factors that could pro-vide alternative explanations for the observed relationship between tion. The Gaussian curve fits were generally the most successful, producing the largest proportion of statistically significant effectseye position and neural activity. relative to chance of any statistical test performed (pooled condition, line G). The power of this approach was undoubtedly diminished Statistical Analyses by the need to either pool across sound location (a parameter that Given the complex pattern of eye position effects, we sought to is clearly relevant to auditory neurons) or perform multiple statistical confirm that the effect of eye position truly differs from chance. tests at the different sound locations. The approach also lacks som
