Activation related to the oddball experiment resulting from second level random effects analysis combining all three conditions (NN, SD_alert, SD_sleepy). Task-positive clusters (p_FDR < 0.0001, extent >30) as well as task-negative clusters (p_FDR < 0.05, extent >30) are reported. Sorting is after Z-values of the cluster peak voxel. Coordinates are given in MNI space. L, left; C, central; R, right; G, gyrus; L, lobule; Nuc, nucleus.
