This is a follow-up, a beans-spilling to as much of
my knowledge as I can type right now. I know I could do better; I’m writing this all
from memory, with only help from the dictionary. This tends to happen with all the writings.
Details collected from the episode of Charlie Rose that aired on November 24, 2009, the ‘vision’ part of a Brain series: the eye has a brain of its own, compresses 100 million receptors on the retina down to 1 million signals for the limited nerve bundle.
Visual cortex impulse feedback from individual cells include line orientation.
I suspect that the individual line orientation data is branch-collected to form shape data
(adjacent lines + directional cues = edges).
The brain, human or not, is remarkably individualistic. The different processes take the immediate stimuli all at the same time, feeding back the results in response on their own.
The consciousness of the frontal lobe (or “soul Input/Output”) sees the world through the feedback of a conductor-like center. This conductorship decides what areas to poll and change. The individual cells take command down the matrix, as signals are processed down the line.
After all is said and done, the results come back to the conductor’s window —
this is what is experienced for the consciousness (that is, unless you’re out-of-body).
Unlike basic computers of the 20th-century, there is no “input center,” no Video RAM for each sense; the different functions receive their input signals as quickly (and directly) as possible for immediate interpretation. This is a necessary feat, as nature needs to do whatever it can to get the biggest bang for the buck. The closer representation for this in computers are the hard drives that’re set up to write directly to RAM without consent of the CPU. But even that example misses the plastic effect of the mind, where any mere ‘control’ stimulation changes the structure at hand. It’s difficult to poll results, even memories without changing them.
Initially expressed genetically, all functions of an organic brain serve as plastic result of their environmental factors and cues, developed by the organism’s behavior, logically split through natural selection. Balance, orientation, tone, amplitude, contrast, shape, texture, color, facial and symbol recognition, and landscape name just a few of the functions of the human brain, developed out of many, many, many generations.
Failure of function has everything to do with the expectations of the caller, and the
blindness or inability of the caller to bypass. Fixed results aren’t subject to neuron
termination, but a prolonged null response is.
What goes where in the creation of a cell depends on a host of procedural cues, and the genes are king. In all normal operation, what makes sense here is what’s called for, just as anything in nature acts on what it likes, and conditioning for what works is excellent. For cell creation to take place, the brain has to be in the mood.
In early development, or in the case of structural impairment, the determined physical ends
are used in recalculating new bounds, and the structures are adjusted to fit the new bounds.
For example, in losing one hemisphere, the remaining brain has to regenerate all functions with
what is available, reassigning unused areas (or now-unused areas, since the ends of the severed
area are now unused) to take over in such regeneration.
Granularity in sample point construction brings the maximum number of levels per stepping in every sensory sense to about 700. (The human eye can see what is known as “banding” in 24 bit images due to it’s limitation of 255 levels per channel.) The receiving end automatically adjusts amplification, thus amounting to very high decibel ranges in sound, and shadow interpretation in vision.
More than the limited 25,000Hz response range for the cilia in the human ear, relative sample rates for the audio portions of the brain top 100,000 for the sake of sound direction. (Due to speed limits of sound, if a distinct sound comes to one ear slightly before the other, then said heard sound is presumed closer to that ear.)
Because there is a lower threshold to mark level zero in communications (anything less is considered signal death), there are actually two thresholds to pain. Endorphins bind to opiate receptors, thus reducing pain and emotion response. It’s not difficult to imagine that a figuratively negative pain level feels gooood. But since all levels in feedback response are adjusted over time for bias, a “negative level” will turn “normal,” and what was considered “normal” is now painful. This is where we get addiction, and the fact that affection doesn’t last.
For athletes, it’s the opposite: they grow the ability to override pain
response, bypassing their upper pain threshold for their work. It’s not difficult to
imagine how excruciating it is at the end of a game. Normally, their brain and body would be
doing whatever it takes to get out of it, even if that means hallucinating. How remarkable
that we sometimes think about the physical strengths of athletes, yet overlook just how much
tremendous mental strength it takes to fully build and act on the field.
The body uses a “tear and repair” method for strengthening organs. When a tear occurs, it is repaired using the material that specific area calls for. All tissues call for proteins, especially muscles in generating more fibers, bones may call for additional calcification, and the brain calls for flexible fats, such as the Omega-3 fatty acids.
During repetition (i.e., exercise), the fountain of youth in gland-generated chemicals is used to restore any part of the body held in that state of wear and tear. For muscles, carbohydrates are used in the case that oxygen debt cannot be filled.
For the stuff figured, I’m kind of turning into a human guinea pig (not really). And
as they say, you tend to get more research from injury than anything else (uh-oh).
Well, I’m sure this page is easier to understand than nonobvious answers to homotopy sheaf
contexts.
For more exploits, the dream page has got additional
information on how sleep and neuronal activity happens... with questionable accuracy.
Do your homework.
