Figure 1

The fixed specimen was photographed after removal of the leptomeninges. Evidence of the surgical lesions in the temporal lobes is highlighted by white geometric contours (a, b). A mark produced by the oxidation of one of the surgical clips inserted by Scoville is visible on the parahippocampal gyrus of the right hemisphere (black arrow). (c) encloses a lesion in the orbitofrontal gyrus that affects the cortex and WM. Marked cerebellar atrophy is consistent with H.M.’s long-term treatment with phenytoin. Scale bar, 1 cm.
