(A) Calculating tuning-curve weights relative to the template orientations in a training data set (in window from –150 to +300 ms around stimulus onset), applying these weights on test data, and sorting them relative to the stimulus orientation, showed decoding early after stimulus onset that quickly returned to baseline. (B) Calculating population weights only on the pre-stimulus period (with respect to the template orientations) yielded a population tuning curve with a significant peak around the presented stimulus orientation (e.g. a significant peak above the average response around 0º, and a significant positive tuning curve slope between ± 90º and 0º). Shading indicates the standard error of the mean. Black bars indicate significant time points or orientations (p < 0.05).
