The framework of systemic psychophysiology has been described. Data were described from studies of unit activity in vitro, and in awake normal and pathological animals learning new behaviours, and realizing previously-learned behaviours (both complex instrumental behavior and simple acts). Data were also described from experiments with human subjects who learned and performed tasks of word categorization and skilled per-

formance, and board games, and who answered psychodiagnostic questionnaires. Based on these descriptions, qualitative and quantitative descriptions of the principles of formation and realization of individual experience were suggested in the framework of a unified methodology. From the authors' point of view, the development of a new system—systemogeny—is considered to be the fixation of a stage of individual development. The performance of a behaviour is the simultaneous realization of many elements of individual experience, formed at different stages of individual development. The dynamics of formation and actualization of the structure of individual experience were thus demonstrated, and the relations among elements of individual experience in different forms of behaviour and at different stages of its formation and realization were described.
