Psychophysiological mechanisms and objectification of the short-term pathogenetic psychosomatic therapy method PSY 2.0

This is the authors' abstract. We don't add key points for this paper.

The article discusses the psychophysiological foundations and mechanisms of action of the PSY2.0 method of short-term pathogenetic psychosomatic therapy developed by M. A. Filyaev in the context of modern concepts of systemic psychophysiology, neuroplasticity, and autonomic regulation. The subject of a detailed theoretical and analytical breakdown includes the key concepts of this therapeutic methodology, such as "biosensory conflict" (BSC) and "somatic marker," as well as the psychological and physiological content of the processes of reactivation, regression, and reconsolidation of autobiographical memory under the influence of new emotional experience. Furthermore, the study examines the diagnostic capabilities of heart rate variability (HRV) analysis and event-related heart rate telemetry. These tools are investigated as objective psychophysiological markers and criteria for registering the dynamics of the functional state of the human central and autonomic nervous systems directly at various stages of psychotherapeutic intervention. The research aims to overcome the shortage of objective criteria for evaluating specific stages of short-term therapy. The methodological foundation of the study is an interdisciplinary approach that integrates the principles of psychophysiology, neuroscience, clinical psychology, and psychosomatic medicine. The methods of theoretical analysis, synthesis, and comparison of scientific publications were applied, alongside the modeling of educational and therapeutic processes. The concepts of P. K. Anokhin and A. A. Ukhtomsky served as the theoretical framework. The scientific novelty of the study lies in the original theoretical substantiation of the PSY2.0 method from the perspective of nervous system functioning and the concept of memory reconsolidation. For the first time, the authors demonstrate that the concepts of biosensory conflict and somatic marker align with limbic system processes, amygdala hyperactivation, and insular cortex functions. The conclusions state that the fundamental premises of the PSY2.0 method do not contradict established scientific data on neuroplasticity and interoception. The study proves the promising potential of combining heart rate variability (HRV) analysis and event-related telemetry for objective, step-by-step monitoring of changes in autonomic regulation (including heart rate, and LF and HF spectral components) during psychotherapy sessions. The authors emphasize the need for cautious interpretation of HRV data in conjunction with clinical observation due to the influence of non-specific factors. Finally, the importance of conducting future experimental and comparative studies alongside cognitive behavioral therapy (CBT), ACT, and EMDR using uniform, standardized protocols is substantiated.
