For the direct contrasts, ″Eye > hand″ result was masked with the stop–go contrast for the saccade task, whereas ″Hand > eye″ result was masked with the stop–go contrast for the manual task. T values, Z values, and MNI coordinates (x, y, z in mm) of the activation peaks in the clusters are listed. Unless otherwise stated, all local maxima were significant after corrected for false discovery rate (p ≤ 0.05). Eye, Saccade inhibition; Hand, manual inhibition. *p < 0.13 (false discovery rate), approaching significance.
