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 ...
Pathoclisis (from -clisis meaning "predisposition" in Ancient Greek) [1] is the theory that certain specialized parts of the brain are the first to be damaged in the case of disease, lack of oxygen, or malnutrition. The selective vulnerability of certain neurons can then lead to the expression of pathology. [2]
Based on a theoretical framework of neurodynamics that draws upon insights from chaos theory, he speculated that the currency of brains is primarily meaning, and only secondarily information. [ 2 ] In "Societies of Brains" and in other writings, Freeman rejected the view that the brain uses representations to enable knowledge and behavior.
The cerebral cortex, also known as the cerebral mantle, [1] is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals.It is the largest site of neural integration in the central nervous system, [2] and plays a key role in attention, perception, awareness, thought, memory, language, and consciousness.
How the Self Controls Its Brain [1] is a book by Sir John Eccles, proposing a theory of philosophical dualism, and offering a justification of how there can be mind-brain action without violating the principle of the conservation of energy. The model was developed jointly with the nuclear physicist Friedrich Beck in the period 1991–1992. [2 ...
Edelman's theory focuses on two nervous system organizations: the brainstem and limbic systems on one side and the thalamus and cerebral cortex on the other side. The brain stem and limbic system take care of essential body functioning and survival, while the thalamocortical system receives signals from sensory receptors and sends out signals ...
Another theory of brain size in vertebrates is that it may relate to social rather than mechanical skills. Cortical size relates directly to pair-bonding lifestyle and among primates, cerebral cortex size varies directly with the demands of living in a large complex social network. Compared to other mammals, primates have significantly larger ...
In their initial experiments, Graziano and colleagues used electrical microstimulation on the motor cortex of monkeys. [15] [19] Most previous protocols in the motor cortex used very brief stimulation, such as for a hundredth of a second. Graziano applied the stimulation for half a second each time, on a behaviorally relevant time scale, in ...
