The Human Biocomputer coined by John C. Lilly, refers literally to the "hardware" of the human anatomy. This would include the brain, internal organs, and other human organ systems such as Cardiovascular, Digestive, Endocrine, Immune, Integumentary, Lymphatic, Muscular, Nervous, Reproductive, Respiratory, Skeletal, and Urinary systems. The biocomputer has stored program properties, and self-metaprogramming properties, with limits determinable and to be determined Potter, page 41.
The functional organization of the human biocomputer Potter, page 68:
Level - Parts
01. External Reality: Biochemical - Chemical - Physical
02. Body: Biochemical Body - Sensory Body - Motor Body - Vascular Body
03. Brain: Biochemical Brain - Neural Brain - Glial Brain - Vascular Brain
04. Signs of activity: Biochemical Activity - Neural Activity - Glial Activity- Vascular Activity
05. Details of instructions: Subroutines - Subroutine Storage
06. Detailed instructions: Programs - Program Storage
07. To Program sets of programs: Metaprograms - Metaprogram Storage
08. To Metaprogram: Self-Metaprogram - Awareness
09. To be Metaprogrammed: Supra-Self-Metaprograms
10. Beyond Metaprogramming: Supra-Species-Metaprograms
11. Above and in Biocomputer: Unknown
The levels of the human biocomputer are explained thus:
Levels from one to two are the boundaries between external reality and the body. Certain energies and materials (heat, light, sound, food, and secretions) pass through this boundary in special places.Levels two to three are the boundaries of body and brain, in which special structures such as blood vessels, nerve fibers, and cerebrospinal fluid pass.
Levels four through eleven are in the brain circuitry, and is the software inside the biocomputer.
Levels after ten are termed unknown. This is to allow an openeness for future scientific research, and discoveries. This is also to illustrate the unwillingness to subscribe to any dogmatic belief, to encourage creative, courageous and imaginative investigation, to emphasize the necessity for unknown factors on all levels, and to point out the heuristic nature of this schema Potter, pages 68-69.
