Neuron-antineuron test for target selectivity. A, C, Response of a representative neuron (A) and LFP site (C) during the visual search task in which a target (thick line) or distractor (thin line) appeared in the preferred location. Middle, The mean area under the ROC curve in a running 10 ms window. B, D, Distribution of average area under the ROC curve in the window 50 ms after array onset until 50 ms before mean saccade response time for SEF and FEF neurons (B) and LFP (D). Asterisks indicate significant difference between areas (***p < 0.001, Wilcoxon rank-sum test).
