How they work
Neurofeedback
Core mechanism: Repeated operant conditioning of brainwave patterns is held to produce lasting shifts in arousal regulation, reducing hyperarousal, hypoarousal, and attentional dysregulation. Whether the learning is specific to the trained frequency, or is a nonspecific effect of sustained attention and reinforcement, remains the field's open question
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 (The Expression of the Emotions, where the vagus appears as the pneumogastric nerve, which Porges cites as an anticipation); MacLean (triune brain, whose evolutionary layering the theory structurally repeats and which comparative neuroanatomy has since abandoned); Dana (clinical translation); Levine (somatic trauma); Merleau-Ponty (body-subject)
Blind spots: Underlying theory scientifically contested; clinical applications extrapolate beyond evidence; not a standalone protocol, and running it as one rather than letting it inform an evidence-based treatment is a misapplication of the framework
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.
