At present in the structure of person activity increases a role a mental activity, so important is a factor study, influencing upon efficiency of mental capacity to work. Interest study of intercoupling mental capacity to work with individually-typological differences of human, since they more stable.

Since, in multiple studies shown that individually-typological differences are defined by different brain structure activity, interesting as they are reflected individually-typological differences of human on mental capacity to work factors and EEG factors. As a result studies revealed influence individually-typological differences as on mental capacity to work factors, so and on factors of EEG rhythms. Discovered that individually-typological differences in source functional condition of brain were reflected on factors of mental capacity to work.
