Brain

I am going to propose a theory for comment. Take it with a grain of salt.

If we look at the evolution of the brain, the earliest animals had brains that were mostly brain stem with only a little cerebral matter. Humans, which are the highest animals have evolved the greatest amount of cerebral matter, pound for pound. The cerebral should be at a higher potential than the brain stem.

If one assumes a cellular potential between the brain stem and the cerebral, than the potential between the brain stem and the cerebral will influence the amount of current stemming from neuron firing/cerebral matter that is needed to connect the potential. This constant potential difference keeps the cerebral matter constantly firing, while the neurons' ability to restore itself manintains the potential. In other words, rather than cerebral just firing for no reason, there may be a constant tug or constant potential that keeps it firing. The firing will lower the membrane potential of neurons thereby bringing them closer to brain stem potential. Unfortunately for the brain stem, neurons recover too fast to remove the potentual. Within this cerebral/brain stem energy flux, the human ego appeared.

Re: Brain

The second part of this theory has to do with the brain stem and body. These set another potential with the brain stem at the higher potential, intermediate to the cerebral. The brain stem will connect the potential to the body using the connecting nervous tissue, for example to maintain some degree of muscle tension. The brain stem can also influence and pertubate the body potential set point through the blood supply via the hypothalamus. For example, fight or flight, lowers the set point potential of the body, via the blood and adreneline, thereby draining and lowering the set point potential of the brain stem. This, in turn, increases the potential to the cerebral matter causing an increase rate of neuron firing. The higher current through the brain stem into the body, combined with the faster cerebral data processing rate gives one an amplified response for the situation.

If one looks at neuron branching, neuron branching implies increased surface tension with the smallest diameter branching defining the highest surface tension. It is loosely analogous to bubbles in water, with the highest curvature bubbles having the highest surface tension. This surface tension is a reflection/indication of cerebral potential. That being said, the lower the potential between the cerebral and the brain stem the higher the potential the cerebral set point can go since the neurons can all be closer to fully recovering from firing. This higher membrane potential is reflected by increased surface tension within the cerebral leading to branching, i.e., toward white matter. The ego helps this process by focusing cerebral output within the cerebral via the imagination.

Conversely, if the potential to the body is higher, the current from the cerebral is higher. This can lower the set point of the cerebral due to the neurons being more often in the recovery mode. The lower average membrane potential or lower surface tension can be reflected by the highest surface tension neuron branching reversing or disappearing due to nonequilibrium, i.e., toward gray matter. Sleep allows a balance or a normalized cerebral set point to be created for forward and reverse branching. Both types of branching are useful for our even changing needs. Sometimes you need to wipe the slate clean, i.e., temporarily lower the cerebral set point with a higher body potential, so one can readapt i.e., increase set point with fresh branching.

Illucid. Go maunder about EEG frequencies and Schumann resonances at 7.8, 14, 20, 26, 33, 39, and 45 Hz,

J. Geophys. Res. 96 15973 (1991)

The spike at 17 Hz is due to Swedish railroads.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
