Stimulus-selective brain activity. A: coronal (y = −48) section showing parametric effects of the probability an image was classified as a face in right fusiform gyrus (FG; 39, −48, −24; z-score = 4.07; P < 0.05, small-volume corrected). B: coronal (y = −42) section showing parametric effects of the probability an image was classified as a house in bilateral parahippocampal gyrus (PHG; left: −21, −42, −15; z-score = 3.68; right: 33, −42, −9; z-score = 5.26; both P < 0.05, small-volume corrected). C and D: percentage signal change as a function of cost condition in stimulus-selective ROIs defined from clusters shown in A and B.
