II.4.b) Human brain structure and efficiency
The efficiency of the brain structure is easily observed as much in intelligence as in memory. The first supports itself on the second so as not to unnecessarily repeat a multitude of operations; it even reaches the formation of what we could call subprograms of automatic action, like the pre-defined responses to different situations when driving.
We could assume that almost half of memory is devoted to storing information about support relations directly to intelligence, independently of whether information from the perceptions is found stored in accordance to a multiple system of references or not.
Likewise, the memory, or better said, the memory manager, will try to save only the information it considers relevant, that which does not already exist or save similar information together, only adding a new nuance to already present information. Further along, we will return this subject when discussing types of memory.
II.4.c) Utilization of idle resources
It is possible that conscious thought is not unique, that is, that not all of it follows the same line of argument, there may be two or more lines simultaneously. Moreover, I would say that human brain structure is designed to allow are almost always at least two. It would be like the existence of a somewhat conscious thought that is, however, in the background.
This should not be confused with situations when we are thinking about two things at the same time; in this case, the two things are in the foreground of thought.
On the one hand, this would be taking advantage of the system's idle resources, and on the other, we would always have an idea in mind when we decide to stop thinking about something or if we obtained our goal by reasoning.
A blank mind can be attributed to two simultaneous thoughts ending at the same time, although normally I think this happens because we try to go back in a sequence of thought; this is not always easy or feasible.
In respect to the fact that computers already do something similar and that they are becoming more and more complicated needs no further explanation.
II.4.d) Maintenance of cognitive capacity
Given the complexity of the intellectual system of human brain structure and the necessity to maintain an optimum operational capacity in relation to the temporal horizons of information, the system needs to reorganize itself daily. This cleaning function is mainly performed while we are asleep.
The fundamental reason why we need to be asleep may be that it is a time when the memory of work and the relational capacity are freed from a multitude of tasks and that, for the exploitation of daily experience and its analysis faced with its possible memorization, the two abilities are needed with a great available capacity.
Bearing in mind the human brain structure, dreams widely represent the work that the memory manager performs when storing certain information. When it does not know exactly what to do, because it lacks sufficient information, it recreates a situation and tries to force the intelligence to dedicate itself; this decision affects the way information is memorized. In this fashion, it will clean short-term memory and not lose information considered important or feel obligated to provisionally save all information related to a specific subject.
When intelligence does not manage to offer a clear decision for complex subjects, people may have recurrent dreams. Certainly the subject is important and the adopted solution will effect on the saving of a lot of other information in different places in the memory, or it will affect the configuration of one of the dimensions where many references are situated.
The degree of difficulty of some relational problems may be so great that, at certain times, the quickest solution to a problem is to forget it and try it later, especially after sleeping. Any experienced programmer knows that, faced with an elemental problem that seems irresolvable, you always have to try to shut down the computer and try again.
In the first case, after sleeping, the short-term memory has been cleaned due to the way human brain structure works. When the human brain analyses the problem again, everything related and in agreement with the priorities or importance of each element will be loaded; this is what allows the analysis to be notably simplified.
After restarting a computer, all the programs and variables in the memory have disappeared and only the necessary programs and variables will be loaded. This assures us that there is free space and that none of the variables have erroneous values that could have been generated in the multiple tests performed by a programmer in the development of his / her programs.
Another yet different example of the way human brain structure works is the human eye. The eye adapts best to sudden changes in luminosity by opening and closing the lids, that is, by restarting the system. The latter is important for those who drive for long periods of time at night. The light from cars that travel in the opposite direction and those that pass provoke sudden changes in the luminosity that can be tiresome for the eyes.
However, it is very interesting to check that, if when faced with a sudden change in light the eye blinks right at the time of the change, eyes fatigue and the discomfort that people suffer from is reduced at least to one third. This means that there are mechanisms that adjust to luminosity and do not cause eye fatigue; these are optimized to work starting in the darkness, and are therefore more efficient when given the appropriate circumstances.
