Neuroplasticity is a double-edged sword. Whereas trauma often results in dysfunctional brain adaptation, neurofeedback can reduce PTSD symptoms by promoting constructive changes. Evidence-Based Practice in Biofeedback and Neurofeedback (4th ed.) has rated neurofeedback for PTSD as efficacious.
The brain orchestrates homeostasis through structures like the hypothalamus. The brain's capacity for neuroplasticity allows it to reorganize its structure and function in response to experience (Voss et al., 2017). The brain often changes in dysfunctional ways in response to trauma. Using magnetoencephalography, Badura-Brack et al. (2017) found increased medial temporal (including the amygdalae), prefrontal, and sensorimotor activity compared with controls.
Neurofeedback trains the brain by providing real-time information about its performance. Z-score training (e.g., sLORETA) compares immediate activity to normative values, displaying differences in standard deviations. The goal is to train toward z-zero standard deviations. Neuroplasticity mediates the constructive changes produced by neurofeedback in disorders like PTSD.

Moss, Shaffer, and Watkins (in press) assigned a level-4 rating of efficacious to neurofeedback for PTSD based on multiple randomized controlled trials.
Conclusion The brain orchestrates homeostasis through structures like the hypothalamus. Neuroplasticity enables the brain itself to adapt its structure and function in response to experience. Trauma often produces dysfunctional changes, whereas neurofeedback can reduce clinical symptoms. The upcoming Evidence-Based Practice in Biofeedback and Neurofeedback (4th ed.) found neurofeedback for PTSD to be an efficacious intervention. References Badura-Brack, A., McDermott, T.
