Dependence of Choice and Periodicity Sensitivity on LFP Spectral Band and Recording Location
(A) Analysis of LFP by spectral band. The LFP was filtered into the bands indicated, and the percentage of significant aROCF0 (stippled lines) or aROCchoice (solid lines) values is shown in different analysis time windows.
(B) aROC values obtained with significant differences indicated by horizontal bars. Frequency bands are ranked left to right from most to least informative.
(C) Electrodes were grouped into those with near and far CFs relative to the stimulus F0. The percentage of significant sites (mean ± SEM) across electrodes is shown in different time windows.
(D) Choice index values across all recording sites which had a significant aROCF0 or aROCchoice value, grouped by CF (mean ± SEM). Asterisks indicate which time points were significantly different from zero (t test, p < 0.05 / 8 = < 0.0063). Red asterisk marks the only time point at which the distribution of CI values was significantly different (two sample t test, p = 0.011).
(E and F) aROC values obtained for significantly informative recording sites according to cortical field.
