How they work
Neurofeedback
Core mechanism: Repeated operant conditioning of brainwave patterns produces lasting changes in arousal regulation, reducing hyperarousal, hypoarousal, and attentional dysregulation
Ontology: Dysregulated brainwave patterns as a substrate of psychological distress. Healing requires direct intervention at the neurological level, not only through meaning-making or behavioral change.
Polyvagal-Informed Therapy
Core mechanism: Identifying autonomic state (ventral/sympathetic/dorsal) + co-regulation with therapist + building ventral vagal capacity
Ontology: Trauma disrupts autonomic regulation; neuroception of danger keeps nervous system in defensive states

What each assumes — and misses
Neurofeedback
Philosophical roots: Behavioral learning theory (operant conditioning); neuroscience; cybernetic feedback systems; Fisher draws on developmental neuroscience and attachment theory
Blind spots: High cost per session; requires specialized equipment; protocol selection is complex; limited standardization across practitioners; evidence base stronger for ADHD than trauma
Therapeutic voice: Watch the screen. When you hear the tone, your brain is doing what we want it to do. Just let it happen.
Polyvagal-Informed Therapy
Philosophical roots: Porges (polyvagal theory); Darwin (emotional expression); Merleau-Ponty (body-subject); Dana (clinical application); Levine (somatic trauma)
Blind spots: Underlying theory scientifically contested; clinical applications extrapolate beyond evidence; not a standalone protocol
Therapeutic voice: That shutdown feeling — that's your nervous system protecting you. It makes sense. Let's see if we can find a little more safety right now.
Choosing between them
Neurofeedback and Polyvagal-Informed Therapy both sit within the Somatic tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
