The following study is concerned with interrelation of efficiency prognosis activity, specifics of brain providing and anthropometrical attributes in the human. Statistically significant correlation of psychological, neurophysiologic

and anthropometrical indices for an estimation of efficiency of prognostic task solution with use of an original psychological computer version method - "Prognosis-2.5" has been already established and published earlier. We have analyzed EEG records changes in subjects of 20 - 48 years (59 persons) at three different tests. The subjects with high indexes of cognitive functions efficiency have shown the most changes.Thus adequate prediction spectral analyses have shown, usually combined with decrease or reduction of alpha-band activity, and its further decrease with the task complexity were usually observed. Simultaneously, the fast activity of beta-band increasing was observed. In some cases according to mapping data the alpha-band activity zone was contracted, as well as the fast activity zone was expended. The more tests complexity increase the better pronounced changes were expressed. In some cases the activity in theta-diapason increased, as well as its zone registration mapping data have shown and/or was expended.The latter have been usually combined with less efficiency or complete error us prognosis even when alpha-activity decreased and as well as beta-activity increased, what have been typical for subject with efficiency prediction. According to our data and literature it might suggest that neurophysiologic features of not successful subjects due to hyperfunction of ascending activating system and insufficiency of cortical regulating influences. Thus, the level of local activation of the cerebral cortex, necessary for optimum course of touch information processing and the solution of the intellectual tasks isn't provided. The program of anthropological investigation included over 50 measuring and descriptive body and the head indices. In the most cases the subjects with effective prognosis have been shown to have muscular constitution type and statistically significant distinctions (10% more) of a conditional index of brain cavity volume. Thus, we have marked above that efficiency of cognitive activity is connected not only with functional indices of the physiological status, but with human body morphological features of the constitutional structure also.
