3.b) Persistence of brain memory

3.b.1. Short-term memory

All the information the brain has used since the last time the system reorganized or performed the maintenance will be in this memory; usually, since the person slept enough time to perform this task.

The degree of conservation or state of the information will depend on the mentioned time and, of course, on the physiological or genetic capacity of each.

This memory will feed mainly on the data that has gone through the auxiliary working memory, from both medium and long-term memory, the experience, and reasoning during normal life through our perception.

Due to historical evolution, this memory is most efficient for approximately 16 hours, reserving 8 hours daily for its maintenance. Admittedly, we do not use all the sleeping time to clean short-term memory; a significant amount of time will devote to the transfer of information from medium-term to long-term memory and other diverse maintenance functions.

There are short-term memory cleaning systems highly recommended, and others advise against strongly. Just say the first will not be easy to obtain if there are elements in the short-term memory that generate tensions and demand the individual's attention. In regards to the latter, the effects of abusive ingestion of alcohol can be an example; this can, in turn, give us an idea of the effects of non-abusive but counterproductive ingestion, especially for the information contained in this memory.

3.b.2. Medium-term memory

Maintaining information as organized as possible optimizes the information contained in the medium-term memory; this will probably make us take information that we cannot organize immediately but that we can store to organize afterward. Therefore, it eliminates duplicated information and permanently saves information, or similar concepts for reference, saving a large quantity of the memory's capacity or information archive.

In the future, it is very likely that computers will always be working, whether by running requested programs or reorganizing.

We can already cite programs that can run automatically: defragmenting and maintenance of the hard drive, cleaning of the Windows system log, search for and downloading of news or updating programs, information compression, and anti-virus.

The expression of medium-term memory is useful but does not precisely reflect the nature of its content.

The information retained for a rather long time is in this memory. However, this period will be more considerable the more the information is relational and contains less concrete information. That is, the information obtained is not only direct but rather by its relation to other information also saved in the memory.

Independently from whether specific information goes to the memory in its original state, like the birthday of someone close to the person, medium-term memory tends to be more fixed as the information transforms into concepts defined by a system of multi-dimensional references.

Over time, concepts will remain in the mention above because precise information usually ceases being useful. If relevant, becomes a part of instantaneous memory or math memory, and the memorized relations will tend to incorporate into the multi-dimensional reference system. Moreover, if required, the system will add a new dimension.

Not all these processes are free from errors; the appropriate mechanisms in the majority of cases can turn out to be inadequate for others.

One of the circumstances most delicate regarding memory occurs when an idea or something repeats many times during a certain period, and especially when it appears as a hypothesis that develops in complicated ways. By the mechanisms in the brain, the information will save in layers corresponding to more fixed concepts or ideas of our brain memory.

Afterward, when our memory manager accesses this information, it will be likely to interpret it as its own already accepted information, just because it is in a deep layer.

The error can be significant –an external idea is supplanting our true knowledge or feelings!

It is called brainwashing, and it is likely to occur, for example, when we read a book that repeats something thousands of times. Each time we read it, the brain has enough time to memorize the idea or transfer it to a deeper layer. Of course, the effect depends on the ideas and individuals.

3.b.3. Long-term memory

This expression is more descriptive than the previous one but also needs some elucidation as far as its nature.

If medium-term memory configures as a multidimensional system, long-term memory is formed independently of the famous 'birthday' by an exclusively multidimensional system in which there are fewer dimensions than in medium-term memory, and the memories configure configures the essential character of a person, not of their knowledge. We are referring to the commonly known as general personalized principles such as justice, equality, liberty, respect, education, the benefit of the doubt, and many more.

Knowledge or concepts reside in the deepest medium-term memory layers, or otherwise stated, in the most superficial layers of long-term memory.

The necessity to re-adapt these principles to a greater or lesser extent produces an exciting effect on personal growth and development. Apparently, the unconsciousness does not like the idea; changing personal principles supposes, to some extent, the recognition of some errors in them; it is also a massive task because all of the remaining memory will change and will need to readjust. In periods of quick development of the character, the person will probably sleep more.

Following the thread, this vision is coherent with the fact that people sleep less, as they get older in normal conditions.

3.b.4. Vital memory

Here, we are not referring to a visual or emotional memory but a special type of memory of a visual-emotional nature that is similar to extra-fast movies when a person thinks there is a probability of dying in a matter of seconds.

The content varies from person to person but usually tends to be a sequence of very symbolic emotive images in chronological order.

Another super special and super persistent memory could be the genetic memory, which contains all of the genetic load transmitted to the descendants.
