Fig 6. Spatial organization of category-selectivity.

All subdural electrodes (SDEs) with significant category-selectivity (FDR corrected q≤0.01) are visualized on the MNI N27 template brain (aligned to Talairach coordinate space) after surface based normalization. SDEs are color-coded by the category of preference (matched to image legends). Compass points denote SDE coordinates (Talairach space) and direction. Left: Pial surface maps of lateral occipital cortex (LOC, top) and ventral temporal cortex (VTC, bottom). Right: inflated surfaces for these regions with the lateral-occipital sulcus (LOS) and mid-fusiform sulcus (MFS) delineated by dark gray shades and white contours, and adjacent sulci delineated by lighter gray shades (TOS, transverse occipital sulcus; STS, superior temporal sulcus; p/aOTS, posterior/anterior occipito-temporal sulcus; CoS, collateral sulcus). In the LOC, all 13 face-selective (red; LH n = 8; RH n = 5) and 9 animate-selective (orange; LH n = 6; RH n = 3) SDEs are localized at or below the LOS, while all 12 place- (blue; LH n = 9; RH n = 3) and 3 tool-selective (green; LH n = 1; RH n = 2) SDEs are localized at or dorsal to the LOS. In the VTC, all 3 animate- (LH only) and 42/45 face-selective (LH n = 27/28; RH n = 15/17) SDEs are localized to-or-lateral to the MFS, while all 43 place- (LH n = 29; RH n = 14) and 9 tool-selective (LH n = 7; RH n = 2) SDEs are localized to-or-medial to the MFS. All 6 word-selective (cyan, LH only) SDEs are localized anteriorly at the intersection of the MFS and aOTS (arrow and black circle), interspersed with animate, tool, and anteriorly-localized face-selective SDEs.
