First experiment. Foci revealed by subtraction of mean activity in left-sided from right-sided attention conditions (or the inverse). Anatomical name, Talairach coordinates, rCBF differences between conditions expressed as a percentage of detection rCBF, andZ scores. Bold, Corrected p < 0.05. GL, Lingual gyrus; sca, calcarine sulcus; GFm, middle frontal gyrus; GFi, inferior frontal gyrus; IFS, inferior frontal sulcus; GTm, middle temporal gyrus. See previous table for other abbreviations.
