Differential effects of learning on theta amplitude and theta-gamma coupling. (A-D) histograms show effects of learning on theta amplitude and theta-gamma coupling where the theta band is divided up into 1 Hz steps from 4-8Hz: (A) Theta amplitude in left IT, (B) Theta amplitude in right IT, (C) Theta-gamma coupling in left IT, (D) Theta-gamma coupling in right IT, In (E-F) histograms show correlations with discrimination performance: (E) Correlation with theta amplitude and theta-gamma coherence in the left IT, (F) same as (E) but for the right IT. *** p < 0.001, ** p < 0.01 and * p < 0.05 vs during learning (A-D) or correlation with behavior (E-F).
