Table 3.
Areas of reliable brain activation for the analysis of trait fatigue prior to the N-Back task. ‘BA’ denotes Brodmann Area; ‘X', ‘Y', and ‘Z' denote the location of the voxel in the cluster with the highest activation; ‘Voxels' denotes the number of voxels in each cluster; ‘F stat.’ denotes the F-statistic associated with the voxel of highest activation.
