First experiment. Foci revealed by subtraction of mean activity in left object single-feature discriminations from dual discrimination. Anatomical name, Talairach coordinates, rCBF differences between conditions expressed as a percentage of detection rCBF, andZ scores. Bold, Corrected p < 0.05. GC, Cingulate gyrus. See previous tables for other abbreviations.
