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 2nd paragraph: "Results-Volumes and Proportions-Males and Females Together: The Principal Brain Regions-The average brain volume in the series of 30 male and female children is 1,312 cm^3 (Table 1). The cerebral hemispheres, exclusive of the lateral ventricles, contribute 86% (1,137 cm^3), the cerebellum 11% (140 cm^3), while the brain stem and total
ventricular system are only 2% (21 cm^3) and 1% (15 cm^3) respectively of total brain volumes. Neither the volume of the total brain nor that of any individual brain structure increased systematically with age over the relatively narrow age span surveyed here (Table 3 Fig. 2A,C,E,G)." |
