Neurophysiology of Possession: Functional Convergence of Biological and Cultural Pathogens in the Paralysis of Prefrontal Inhibitory Control

This article proposes a neurobiological model to explain how extremist ideologies and digital stimuli act as 'cultural pathogens' that hijack the human brain. By exploring the concept of 'Functional Convergence,' the author compares the mechanisms of biological parasites, such as the Rabies virus and Toxoplasma gondii, with the impact of 'memetic dominance' on the prefrontal cortex. The study argues that modern digital algorithms saturate the reward system with 'cheap dopamine,' leading to functional atrophy in the brain's inhibitory control centers. This neurophysiological paralysis results in behaviors that prioritize memetic propagation over genetic survival, providing a biological explanation for phenomena such as declining fertility rates and extreme social polarization.
