In vivo measurements of the relative weights of gray and white matter in the human brain

Abstract
Using the intraarterial clearance method with a diffusible inert radioactive gas to determine the cerebral blood flow, one can estimate the relative weight of hemispheric gray matter. In a series of 23 subjects without any organic brain disturbances, the relative weight of the gray matter was found to be 48.8%[plus or minus]S.D. 4.5. In various brain diseases the relative weight of the gray matter was reduced especially where the condition was connected with general atrophy or dementia.
