Table 1.

Cortical neuronal injury was determined using a neuropathology scoring system based on the occurrence of the most severe pattern observed in 40 visual fields. Higher scores represent more severe neuronal damage. Representative photomicrographs are shown in Supplementary Figure S6.

Score	Morphology of Cortical Damage	Ratio of the Most Severe Pattern per Area
0	No damage
1	Scattered	<20%
2		21–50%
3		>50%
4	Grouped	<20%
5		21–50%
6		>50%
7	Panlaminar	<20%
8		21–50%
9		>50%
