238Visuospatial capabilities are an important compo nent of human cognitive activity. They determine human abilities in many fields of activity, from naviga tion tasks to professional skills, because architecture, engineering, surgery, and many other occupations need a high degree of development of this function. In the literature there is convincing evidence of men's superiority over women in the performance of visuospatial tasks, whereas women are superior to men in verbal tests [1][2][3]. The differences presented in the literature are to a large extent determined by the visual task performed. The following experimental models are used: the odd ball paradigm [4][5][6][7], judg ment of the line orientation [2,8], and mental rotation in two and three dimensional space [1,[9][10][11]. It is known that the difference is most evidently demon strated in the tests on figure mental rotation in 3D space: the classical Shepard-Metzler test [1,10,11]. Other tests show either a smaller difference [1] or even its absence [12,13].The methods of electrophysiology and functional metabolic mapping have shown that the gender differ ences in the visuospatial functions are determined in many respects by the peculiarities of their neurophysio logical support [6,11,[14][15][16][17][18][19]. For example, some data in the literature show the higher amplitude of the waves of visual evoked potential in women compared to men, both in response to simple stimuli (light flash) [20] and during the performing of complex visual tasks: the Stroop color test [21] and discrimination of minor dif ferences in the sequence of visual stimuli [6]. A substan tial amount of literature data shows different topogra phy of activation during performance of visuospatial tasks. For example, men compared to women show greater involvement of parietal areas in the task of men tal rotation [22] and pronounced right hemisphere pre dominance during visual task performance [14]. The studies with functional magnetic resonance tomogra phy revealed the gender differences in the cortical acti vation pattern, that combined with the behavioral simi larities between genders [16,17]. They may be based on the gender related peculiarities of the morphology of the visual system. The study [18] describes the gender related dimorphism of the cytoarchitectonic struc ture of the striate regions V1, V2 and the movement related parietal complex V5/MT + hOc5. The greater size of these zones in men, according to the authors offers the possibility of more information processing about visual scenes. There are data on gender specific differences in the maturation of the visual attention sys tems associated with the frontal and parietal areas [23]. The morphological basis of gender differences in the visual perception may also be due to the difference in the ratio of white and gray matter of the brain, which is higher in men [24].Analysis in the literature showed that, regardless of the index of brain activity is analyzed by the authors, most of them indicate the gender related strategy ...
