BACKGROUND: Human posterior associative cortex, including its temporoparietal–occipital subarea, is important in cognitive control, verbal activity, sensory stimuli processing, and attention regulation, visuomotor responses, situational decision making. Despite data suggesting the prolonged formation of these higher mental functions during postnatal ontogeny, cortex has been insufficiently characterized with respect to microstructural transformations individual functionally specialized zones...

Aim: This article is devoted to the study of age-related changes in body volume pyramidal neurons (VP) human prefrontal (PFC) and posterior associative cortex (PAC) children from birth 7 years age. Methods: The material consisted left cerebral hemispheres obtained 60 male individuals. We studied areas 8, 45 10 PFC area 37 subareas 37ac, 37a, 37d PAC. For morphometry cortical sublayer III3, we used virtual images serial frontal paraffin sections thick stained by Nissl. determined mean value...

С применением гистологических и количественных методик изучали структурные преобразования пирамидных нейронов фиброархитектоники префронтальной задней ассоциативной коры большого мозга у детей от рождения до 6 лет. Показано, что значимые микроструктурные отмечаются на первом году жизни, а также к 3 5 годам. Выявленные изменения по темпам срокам соответствуют основным возрастным этапам становления высших регуляторных механизмов мозговой деятельности с участием исследованных корковых формаций...
