(自體的心理學)(車行哲學) There are The Three-Stage Model of Addiction (George Koob, Nora Volkow, 2010, 2016). Are there neurobiological models for perversion? (ChatGPT, 2025-5-26)

Yes, there are emerging neurobiological perspectives on perversion, though they are far less developed and less systematized than models like Koob & Volkow’s Three-Stage Model of Addiction. The concept of perversion, historically rooted in psychoanalysis, is being re-examined through neuroscience and affective neuroscience, especially in the context of compulsivity, sexual behavior, and social cognition.


Here are some key directions in which neurobiological models related to perversion are taking shape:





1. 

Perversion as Compulsivity (Orbitofrontal-Striatal Dysregulation)



  • Overlap with OCD and addiction: Certain perverse behaviors—especially paraphilic disorders—are theorized as compulsions with dopaminergic dysregulation in fronto-striatal circuits, similar to what is seen in addictions or obsessive-compulsive spectrum disorders.
  • The orbitofrontal cortex, ventral striatum, and anterior cingulate cortex are involved in inhibition, reward evaluation, and moral decision-making—regions implicated in both addiction and perverse behavior.



Neurobiologically, perversion may involve impaired top-down control over instinctual drives, paired with hypersensitized reward learning circuits.





2. 

Reward Circuitry and Sexual Reinforcement



  • Mesolimbic dopamine pathways (ventral tegmental area → nucleus accumbens) are implicated in sexual arousal and reinforcement.
  • In paraphilic disorders (e.g., voyeurism, exhibitionism), there’s evidence that aberrant stimulus-reward associations get formed, possibly through maladaptive plasticity.
  • Some models propose a sensitization model—where certain cues (e.g., specific fetishes) become pathologically overvalued, akin to incentive salience in addiction.






3. 

Attachment and Affective Neuroscience



  • Perversion in classic psychoanalytic theory often involves object use rather than mutual relationality.
  • From a neurobiological lens, this may reflect early attachment disruptions—linked to oxytocinergic and limbic dysfunctions (amygdala, hippocampus, insula).
  • Neurodevelopmental trauma may shift the individual toward using others as instruments of arousal, possibly via blunted empathy and altered mirror neuron activity.






4. 

Theory of Mind and Empathy Networks



  • Neuroimaging studies of individuals with paraphilic tendencies (e.g., pedophilia) often find reduced activity in the medial prefrontal cortex, temporo-parietal junction, and posterior cingulate—regions involved in empathy, perspective-taking, and moral reasoning.
  • This supports the idea that perversion may involve failures in mentalizing and relational attunement.






5. 

Endocrine and Neurochemical Factors



  • Hormonal factors (e.g., testosterone, cortisol, oxytocin) influence sexual arousal, aggression, and social behavior, and their dysregulation is under investigation in cases of pathological sexuality.
  • Serotonergic dysfunction, as seen in impulsivity and certain personality disorders, is also implicated in some perverse behaviors.






Summary Table

Neurobiological System

Potential Role in Perversion

Dopaminergic Reward System

Aberrant stimulus reinforcement, compulsive seeking

Prefrontal Cortex

Impaired inhibition, moral reasoning deficits

Limbic System (Amygdala, Insula)

Dysregulated emotional processing and empathy

Mirror Neuron System

Reduced resonance with the other, objectification

Oxytocin/Attachment System

Early relational trauma, affect regulation deficits





Caution:



The term perversion is psychoanalytic and value-laden. Contemporary neuroscience tends to use descriptive categories like “compulsive sexual behavior,” “paraphilic disorder,” or “hypersexuality.” Thus, while neurobiology can illuminate some correlates, it cannot capture the symbolic, relational, and meaning-making dimensions emphasized in psychoanalytic theory (e.g., Lacan’s idea of perversion as “a pact with the Law”).
