(A) Tuning curve amplitude for stimulus orientation, estimated by calculating weights at one time point and applying them to test data at all time points in a trial. While decoding is consistently high along the diagonal (in the time window that contains significant stimulus information, between 52 and 544 ms, significant cluster indicated by color saturation/opacity), the slope drops sharply at off-diagonal train-test time coordinates. This indicates that the discriminative patterns are not consistent across time—rather they change rapidly, even while the stimulus can be readily decoded (i.e. off-diagonal decoding is significantly lower than on-diagonal decoding, black outline). B and C show the same analyses as in A, but sorting all trials by the template angle and the decision-relevant angular distance, respectively.
