Biological determinants of the personality: gender, type of nervous system and temperament, functional asymmetry of the brain. /part 4/

in #godflesh6 years ago (edited)

Many scholarly researchers have dealt with distinguishing personal differences among people, some of whom oppose typology and claim that we all develop our own unique lifestyle. This may include such desirable and undesirable traits, such as vitality, social interest and optimism, or selfishness, arrogance, vanity, hostility and helplessness. Every person is at least somewhat unique and the above terms are used only because our language lacks sufficient precision to describe all the subtle nuances that distinguish one human being from another.

Current research has shown that the structure of the nervous system properties as neurophysiological dimensions of temperament are much more complex, and the main combinations of these properties - much more, and their quantity is not limited to the four types described above. More researchers from the past have noted the many combinations of the different properties of temperament types, calling these combinations a complex type of temperament. In fact, most people have a very sophisticated temperament. Different combinations of temperament can be both natural, ie. both inherited and acquired, when, under the influence of the life of the world, the basic temperament is softened by another that complements it. According to Lascal, one temperament can be combined with another, and this is characterized by the presence of certain individual traits, manifesting both in the appearance of man and in the properties of his inner world.

The two brain hemispheres of man are not symmetrical mirror images of each other. Their asymmetry starts from embryonic development and at birth in about 65% of individuals the surface of the temporal lobe of the left hemisphere is larger. Functional brain asymmetry is also referred to as the priority of one hemisphere, the lateralization of cognitive processes. Only cognitive processes are asymmetric with respect to the two hemispheres. Brain hemispheres are functionally asymmetric. With existing anatomical asymmetry, it has not yet been established which exactly corresponds to functional asymmetry. According to some authors there is a connection between functional and anatomical asymmetry - so it is found that the silvian furrow is longer and deeper in the hemisphere where the tongue is etched - this is definitely established. According to other authors, there is no relationship between anatomical and functional asymmetry of the brain. Information on functional brain asymmetry is also derived from the pathology. Localization, however, in pathology does not completely overlap with the localization of the process in the healthy individual.

The most striking is the brain asymmetry in terms of language functions. Brain hemispheres are connected to each other by a corpulent body and normally manipulate sensory information bilaterally. Nevertheless, the system for processing this information differs. In each person there are individual peculiarities of the domination of a hemisphere of the tongue and of the non-linguistic processes.
