aX, Y, and Z are Talairach coordinates. We computed a reconstructed representation of stimulus orientation using multivoxel activation patterns measured in each ROI during attend-orientation scans. p refers to the proportion of 10,000 bootstrap permutations where the amplitude of the reconstructed representation was ≤0 (FDR corrected). dlPFC, Dorsolateral prefrontal cortex; IPL, inferior parietal lobule; iIPS, inferior intraparietal sulcus; IT, inferior temporal cortex; LH, left hemisphere; lPFC, lateral prefrontal cortex; OFC, orbitofrontal cortex; RH, right hemisphere; sIPS, superior intraparietal sulcus; SPL, superior parietal lobule; vlPFC, ventrolateral prefrontal cortex.
