Electroencephalographic Correlates of the Speed (TIME) of the Central Processing of Information by the Higher Parts of Brain in Humans with the Different Individual-typological Features of the Higher Nervous Activity

The speed (time) of the central processing of information (SCPI) by the higher parts of brain and electric activity of the cerebral cortex were studied using the method of electroencephalography (EEG) in humans with the different individual-typological features of the higher nervous activity – functional mobility of the nervous processes (FMNP). The statistically important differences of indices of the complicated sensorimotor reactions of differentiation, SCPI and EEG powers between the groups of examined were established. The persons with the high FMNP level were characterized with the reliably higher CPI speed and power of α-rhythm of the convexital surface of the cerebral cortex, especially right hemisphere and β-rhythm of EEG (р≤0,001) comparing with examined persons with the mean and low FMNP levels. The correlative analysis proved the reliability of the connections between FMNP, SCPI and EEG characteristics. We think that the established EEG-correlates of the central processing of information by the higher parts of brain increase the predictability of analysis of typological features of the higher nervous activity and can be useful in the field of professional orientation and selection and also in psychodiagnostics of neurological disorders
