FIG. 3.

ECoG category selectivity. A and B: Example responses of word- and face-selective sites from case 1 (A) and case 2 (B). C and D: Spatial map of contrasts of words > scrambled, and words—faces in the window 100–400 msec after stimulus onset for case 1 (C) and case 2 (D). Thresholded by electrodes with a significant difference (2-sample t-test, p < 0.01). Electrodes in black were excluded due to excessive interictal spikes. Preoperative MRI-derived mask of pathological tissue is highlighted in purple.
