Group time courses during the noise/motion period as a function of whether a motor response was executed (filled symbols, hits, response; open symbols, misses, no response). Time courses are based on the ROIs used in the ANOVA to evaluate the effect of response/detection on activation. The top two rows show responses in motion-sensitive occipital and parietal areas. Activations were significantly larger when targets were missed and search could not be terminated. The bottom row shows activations in two frontal areas that were unaffected by response execution and target detection.
