8-OHdG Levels in Human Control and ALS CNS Regions^a

CNS Region	8-OHdG Concentration (pg/μl, mean ± SD)
	Control	ALS
Motor Cortex	24 ± 11	35 ± 15*
Somatosensory Cortex	32 ± 14	29 ± 12
Spinal Cord-ventral horn	17 ± 7	27 ± 13*
Spinal Cord-dorsal horn	15 ± 11	18 ± 10

^a8-OHdG levels were measured by ELISA. Tissue samples were obtained

by careful anatomical micropunch technique
