FIG. 1.

Extraoperative ECoG category selectivity. A: Examples of stimuli from the visual category localizer. B: Time course of BGA for representative stimulation-positive electrodes from 4 patients. C–E: Contrasts of words > scrambled (C), words > consonants (D), and words—faces (E) in the window 100–400 msec after stimulus onset. Thresholded by electrodes with a significant difference (2-sample t-test, p < 0.01). F: Concordance between task-related activation (words > scrambled; ECoG+) and CSM sites in vOTC, leading to reading disruption (CSM+). CSM was performed between neighboring electrode pairs. Pairs were considered ECoG positive if either electrode was significant.
