Rendered in Cinema4D The 8-Circuit Model of Consciousness is a model of consciousness proposed by Timothy Leary. Leary believed the mind is best viewed as a collection of 8 "circuits", also called "gears" or "mini-brains". Each stage is claimed to represent a higher stage of evolution than the one before it. Leary presented a model based on the lateralization of brain function but taking his conclusions further than orthodox neuropsychology warrants. The first four levels, which Leary presumed to reside in the left lobe of the cerebrum, are concerned with the survival of organisms on earth; the other four, which Leary suggested are found in the right lobe, are for use in the future evolution of humans, and remain dormant in the majority of human beings. This model was never accepted by the mainstream scientific community. The eight circuits explicated by Leary are: The Bio-survival Circuit is concerned with the earliest modes of survival and the basic separation of objects into either harmful or safe. This circuit is said to have first appeared in the earliest evolution of the invertebrate brain. It is the first to be activated in an infant's mind. Leary says this circuit is stimulated by opioid drugs. This circuit introduces a one-dimensional perception: forward and backward (i.e., forward towards food, nourishment and that which is trusted as safe, and backwards -- away from danger and predators).
