Figure 6

Spatial characterizations of ΔP1 and ΔITPC. ΔP1 (A) and ΔITPC (B) as functions of physical distance from the P1 local focus. Median and error bars indicating 25 and 75% quartile deviations are provided. Black arrowheads in (B) indicate the local maxima of ΔITPC. Shaded areas indicate the ranges of half-widths in relation to the local maxima. Thick horizontal bars indicate that ΔP1 or ΔITPC at a given distance are significantly smaller than the local maxima (Mann-Whitney U-test with Bonferroni correction, p < 0.05). ITPC (C) and ΔITPC (D) in the low-gamma band as a function of tonotopic distance (ΔCF in octave). Two-sided t-test, **p < 0.01.
