THE CYTOARCHITECTONICS OF THE CORTEX OF FIELD 7 OF THE SUPERIOR PARIETAL AREA OF THE BRAIN OF A PREEMINENT SOVIET WRITER
Many modern neurosciences are engaged in the study of the morphological and physiological characteristics of the human brain associated with its talent. The most popular method for studying the creative process is magnetic resonance imaging, which allows one to analyze the structures and neural networks of the brain during its work, but this method does not allow describing the fundamental foundations of neural processes. Describe the morphological features of the microscopic structure of the brain of talented people that underlie its work, possibly using cytoarchitectonic methods. The superior parietal cortex performs important integrative functions by influencing the network of cortical and subcortical structures involved in the processing of cognitive information, having extensive connections with the nearby areas of the cortex and the frontal region. It takes an active part in visual control of movements and analysis of space, in switching and maintaining attention and participates in memory processes, playing an important role in episodic memory, and also participates in the restoration of visual images and the processes associated with the memory of words. The aim of the study was to study the features of the cytoarchitectonic structure of the cortex of field 7 of the brain of a preeminent Soviet writer. The study was carried out on the complex of electronic-optical image analysis «DiaMorph» (Russia), histological sections of the brain of a preeminent Soviet writer and sections of 5 brains of usual men in the control group of the same age were studied. On sections stained with cresyl violet according to the Nissl method in the cortex of field 7, the area of the profile field of neurons, the density of neurons, the density of neurons surrounded by satellite glia, the density of satellite glia and the density of common glia, as well as the thickness of the cortex and the thickness of its cytoar-chitectonic layers were studied. As a result of the study, important differences in the values of the studied characteristics of the cerebral cortex of the Soviet writer and the brain of men in the control group were revealed - a large value of the profile field of pyramidal neurons, a high density of neurons surrounded by satellite glia, and a high density of satellite gliocytes. The discovered features of the brain structure of a talented Soviet writer can be considered as morphological prerequisites for a person's giftedness.
