Figure 1From: Characterization of local invariances in the ascending ferret auditory system95% confidence interval in frequency for the highest responses in in A1 and PEG. Left: with pure tones stimuli. Right: with bandpass noise stimuli. The higher values found in PEG compared to A1 demonstrate higher invariance to frequency shifts in PEG than in A1for both stimuli (p < 0.001, one-sided Mann-Withney U test).Back to article page
