Comments "From the data on the rate of oxygen consumption of the brain presented in table 1 (BNID 110632), it is apparent that its energy output is quite substantial, indeed one of the highest of all the organs of the body. Consuming oxygen at an average rate of 3.5 ml per 100 gm per min., a brain of average weight, approximately 1,400 gm, accounts for a total oxygen consumption of 49 ml per min. or almost 20 per cent of the total basal body oxygen consumption of the normal young human adult. Kennedy and his associates (primary source) have found even higher cerebral metabolic rates in childhood (fig. 1), approximately 40 per cent higher, so that in a 5-year old child, for example, the brain, which at this age has reached close to its mature size, may consume half of the total body oxygen uptake."
