IPD variability across azimuth. A, IPD variability (SD of the cue over different directions of concurrent sources) increases as a function of target source direction. B, Top, ITD-tuning curve widths of ICx neurons increase with preferred azimuth. Bottom, Mean maximum firing rate of ITD-tuning curves shows no correlation with preferred azimuth. C, Normalized (from 0 to 1) SD of IPD (red) correlates well with the increase in widths with azimuth (normalized by the median width at each direction).
