Mean ± SD of the mean and median (in parentheses) EqLC as a function of luminance contrast in the achromatic grating. Data are presented for the two monkeys (T and K) separately. The leftmost column shows the number of neurons for which EqLC could be determined and (in parentheses) the number of neurons that were investigated using the respective stimulus configuration. EqLC SD is presented for stimulus conditions in which nulling occurred for all cells.
