RESUMEN
Principles of designing software and hardware for new computer equipment for psychophysiological examination were elaborated on the basis of theoretical prerequisites and of analysis of the use of equipment manufactured serially for quantitation of indices of the human higher nervous activity (HNA). The hierarchic structuring of software and hardware enabled, through unification of solutions, the development of new modifications of two equipment sets: computer-based unit "Psihomat" KPFK-99 for psychophysiological examination and computer-based unit "STABILOTEST" ST-01 for the evaluation of the central nervous system by the stability parameters in maintaining the vertical posture. The units have new improved functional features and provide the users with new computer technologies for dealing with research and practical tasks related with examination of human HNA parameters in health and pathology.
