P.726 left column bottom paragraph to right column top paragraph: "The present report is a volumetric analysis of the brains of primary school age children (age 7-11 years), equally divided among males and females. The age range of subjects lies in the final critical phase of brain growth where subsequent volumetric increments will be small. The analysis is based upon three-dimensional magnetic resonance image (MRT) acquisitions and an analytic procedure which has already been applied to a series of normal young adult brains (Filipek et aL, 1994). Thus, the present series of data for the not-yet fully grown child's brain is comparable with a published reference series which provides the adult expectations of growth. The analysis considers whether among 7-11 year old children as a group there are differences in the patterns of volumetric increase among separate structures of the brain and, if present, whether such different patterns are sexually dimorphic." |

P.727 right column 3rd paragraph: "The Cerebrum-The total cerebral volume is ~67% gray matter structures and 33% white matter (Table 2). The neocortex, mean volume 700 cm^3, is 62% of the total volume of the cerebrum. The neocortex constitutes 92% of the total gray matter volume of the cerebrum and is variably some 60-165 times the size of the other cerebral gray structures. Of the other cerebral gray matter structures, the central gray nuclei are largest at 21 cm^3, but this is only ~3% of the total cerebral gray matter. None of the other cerebral gray structures measured in this analysis contributed >1% of the total cerebral gray matter. The ratio of total cerebral gray matter (neocortex, hippocampus, basal ganglia, amygdala, central gray nuclei) to central white matter in the cerebrum is 2.0:1." |
