Response categories capture important features of the substantial diversity of cortical responses. A: the matrix illustrates the distribution of correlation coefficients for the response PSTHs concatenated across the 5 standard durations at a temporal resolution of 25 ms. The color bar indicates the value of the correlations. B: this matrix indicates the median duration discrimination performance for the cells in each response category (grouped by rows) when the spike trains to be classified are compared against different templates, grouped by columns. The color bar indicates the mapping of discrimination performance (in percent correct) to color; for convenience, the values indicates by the colors appear within each cell of the matrix.
