Control Experiment 1. A, Flattened cortex (left hemisphere) showing t-score maps representing the contrast arm movement versus fixation (green) and fixation versus arm movement (red) for Monkey U (p < 0.05, FWE corrected). B, C, Percent signal change per condition for Monkey U during Arm. Baseline is PSC during fixation without distractors. *p < 0.05 corrected for multiple comparisons (compared with baseline). Black bars represent the SEM across runs. B, Sacc network. C, Arm network.
