Fig. 3. Adaptation decorrelates population responses.

a: Correlation coefficients between pairs of neuronal bins measured with the uniform stimulus ensemble (n=5). The values on the diagonal are scaled to 1. The subsequent panels have the same scaling factors.

b-c: Correlation coefficients of responses fitted by uniform tuning curves (b) and predicted by adapted tuning curves (c).

d-f: Same as a-c for responses to stimuli in the biased ensemble. The homogeneous tuning curves incorrectly predict a central peak in correlation (b) whereas the fits by the adapted tuning curves correctly capture a diagonal matrix (c).
