The eight-circuit model of consciousness is a holistic model originally presented as psychological philosophy (abbreviated "psy-phi"[1]) by Timothy Leary in books including Neurologic (1973) and Exo-Psychology (1977), later expanded on by Robert Anton Wilson in his books Cosmic Trigger (1977)[2] and Prometheus Rising (1983), and by Antero Alli in his books Angel Tech (1985) and The Eight-Circuit Brain (2009), that suggests "eight periods [circuits]" within the model.[3] The eight circuits, or eight systems or "brains", as referred by other authors, operate within the human nervous system. Each corresponds to its own imprint and subjective experience of reality.[4] Leary and Alli include three stages for each circuit, detailing developmental points for each level of consciousness.[5]
The model lacks scientific credibility and has largely been ignored in academia.[n 1][n 2]
