Details on the observed clusters of activation for contrasts from all three tasks are presented.

From left to right, columns represent the label for each area as used throughout the paper, the MNI coordinates of the voxel in each cluster with maximal T-value, the maximum T-value and the number of voxels in each cluster. The contrast for which the clusters are listed are named on top of each list of activations. At the right side of each contrast name the minimum cluster size is given for a cluster to be considered significant at the group level. That is, clusters with a lower cluster size are statistical trends. Trends are presented for the sake of completeness, and only discussed further when confirmed by significant findings from PSTH analysis (see figure 5). The quoted regions ‘lateral and medial FEF’ and ‘antisaccade FEF’ are also referred to as such in the text and further explored in the PSTHs, and where labeled such for sake of simplicity. Technically it is of course debatable whether all regions could be considered part of a single human FEF region. In general, when a label contains ‘FEF’ it is meant that it was located somewhere along the precentral sulcus or premotor cortex. Abbreviations: FEF: frontal eye fields, SEF: supplementary eye fields, PUT: putamen, CN: caudate nucleus, SC: superior colliculus, SNpr: substantia nigra pars reticulata, RN: red nucleus.
