Abstract

As the surveyed 22 men, right-handed persons, age 18-23 years, the students of 1-4 courses of the Kyiv National Taras Shevchenko University took part in research. Each of the surveyed passed 2 computer subtests: subtest №a 1 "Logical selection" of the Intelligent Structure Test (IST), that investigates the inductive thinking, feeling of language, and subtest № 2 "Definition of the common features" - determinations of capacity for abstracting, generalization, operating verbal concepts. Both these subtests attribute to research of verbal to the component intellect. In all inspected registered an electroencephalogram (ЕЕГ) during realization of testing. In every taking for the frequency ranges of ЕЕГ- delta(0,5-3,9 Hz), theta (4,0-7,9 Hz), alpha(8-12,9 Hz), beta 1(13,0-19,9 Hz) and beta 2(20,0-35 Hz) the mean power of spectrum and the dominant frequency of spectrum was calculated. As a result of undertaken a study it was educed that at research of activity of cerebrum of men subtests of verbal intellect the "Logical selection" of IST and "Determination of general lines" decided within the framework of the common neuronetwork, however at logic selection in a greater degree there was a synchronized activation of the central and parietal zone of the left hemisphere and an occipital zone that has provided complex logical - semantic analysis of the verbal information, the analysis of sense of offers and words with attraction of an associative cortex, and at definition of the common features - activation of specific processes of the semantic analysis in the left frontal zone, definition of sense of words in zone Wernicke and figurative representation of words in the right associative cortex was observed
