Kochura D. Neurodynamic correlates of sensory sensitivity in young females depending on the properties of temperament

The thesis is devoted to defining of neural correlates, which determine differences in the different modalities stimuli perception in young women with extreme temperamental properties. Women with high level of anxiety and neuroticism are characterized by high cerebral lability, excitation dynamic and intensity, which cause the acceleration of the early light adaptation, increased auditory sensitivity, decreased tactile sensitivity and proprioreception. The balance shift toward inhibition and background activity reduction lead to simple sensomotor reactions and late adaptation slowing. The women with high level of psychomotor activity characterized by high excitation intensity and low excitation dynamic, poor background activity and low nervous system endurance. Excluding proprioreception and tactile sensitivity, all sensitivity indicators are better regard to the group with low activity. Aggressive and extroverted women have some similarities with the active women: it is typical of them to have high excitation intensity, low excitation dynamic, high inhibition dynamic, high cerebral lability, and low nervous system endurance. Similarity in sensory areas is expressed in the absolute auditory and visual sensitivity improve. At the same time, in the aggressive women are reduced the visual distinction responses rate, are slowed the early light adaptation, are increased terminal auditory threshold. Their differential thresholds of tactile and motor sensory are generally better. In extroverts the later light and dark adaptation are reduced, and the differential thresholds of tactile and motor sensory system are increased. Thus, the same nervous centers perform the different stimuli perceive in women with various temperamental properties. The baseline activation of these centers are different and relate to the temperamental features.
