title: Variability in the structure of field 39 of the lower parietal area of the cortex in the left and right hemispheres of adult human brains.
abstract: The cytoarchitectonics of field 39 of the lower parietal area of the cortex in the left and right hemispheres were studied in normal individuals and professionally gifted world-famous people. Series of frontal sections were studied, stained by the Nissl cresyl violet method. The profile area of neurons was measured in layers III and V and the distribution of neurons in terms of this property was analyzed. Gifted people showed a significantly greater level of individual variability in the measures recorded here, especially in the right hemisphere, with larger proportions of very small and very large neurons.
