  1. Talairach coordinates of activation peaks revealed by a conjunction analysis of the maintenance period of complex trials versus maintenance period of simple trials conjunct over all four delay durations (FDR-corrected, p < .001; k > 20). Anatomical labels of peak activations are listed in boldface and significant sub-peaks are listed without boldface. Abbreviations: BA = Brodmann area; r = range of nearest gray matter in mm; R = right hemisphere; L = left hemisphere.
