ANS Regulation Theory: Understanding Trauma Responses

Babette Rothschild, a prominent psychotherapist and trauma specialist, provides a detailed understanding of trauma through her theory of Autonomic Nervous System (ANS) Regulation (Rothschild, 2000, 2017).

Neurofeedback and Biofeedback

Neurofeedback and biofeedback are physiologically targeted interventions that train regulation of the nervous system by providing real-time feedback on brain or body signals. In psychotraumatology, they are used to restore autonomic flexibility, dampen hyperarousal, reduce dissociation, and improve attention/affect regulation—capacities often eroded by trauma. Foundational principles Operant conditioning of physiology: clients learn to increase desirable
