Dear Sir,
You have brought in a very important aspect involving ATP etc. which we wish you could have elaborated. The same mechanism that energizes the sodium-potassium pump also energizes the senses to receive and send external impulses to the brain.
The nervous system uses electrical and chemical means to help all parts of the body to communicate with each other. The brain and spinal cord make up the central nervous system. Nerves everywhere else in the body are part of the peripheral nervous system. The peripheral nerves run from the spinal cord to all parts of the body. They surround all the organs, muscles and tissues--the heart, liver, intestines, lungs, skin and blood vessels. The peripheral nerves pick up information about the body and send messages through the spinal cord to the brain. The brain sends messages via the spinal cord to peripheral nerves throughout the body that serve to control the muscles and internal organs. The somatic nervous system is made up of neurons connecting the CNS with the parts of the body that interact with the outside world. But the brain lacks pain receptors (nociceptors) - hence it cannot sense anything. What we feel when we have a headache is not our brain hurting -- there are plenty of other areas in our head and neck that do have nociceptors which can perceive pain, and they literally cause the headaches. Since brain lacks sensory receptors, it does not hurt to have brain surgery.
An object receives all wavelengths of light, but reflects only few after absorbing the rest. That gives the object its color. We see only through eyes because eyes only can measure electromagnetic radiation (measurement is a system of comparison between similars). We feel only with our skin when something comes in close contact. Thus, what we see is the radiation emitted by the object, whereas what we touch is not the radiation, but the body emitting radiation. In both cases, our information is incomplete. When these are carried to the brain, these are mixed and a composite picture is prepared. Emotions are cognitive responses to sensory stimuli after they have been processed.
This picture is measured (compared with similar responses earlier) with memory. Then the perception is matched with the earlier perception of similar impulses. If it matches, we "know" that "it (the concept arising from the perceived impulses) is similar to that (an earlier perceived concept). Hence it (the object of perception) is that (equivalence of the concept).
Modern research on consciousness is confined to the actions of neurons, which is the process and not the perception itself. We must differentiate between the observer, the observed and the process of observation. Thus, modern research is wandering aimlessly.
Finally, thank you very much, because your paper gives much food for thought.
