3.4 Data integrity
3.4.1. Compression of information
Now that we have commented on the types of memory, as you get further into the layers of brain memory, the nature of the information changes into a multidimensional system, or similarly, the information being compressed.
This process takes time and the memory manager needs to use a lot of its power. Normally, it not only deals with information compression, but rather with its decompression, its analysis, and comparison with new information. Then it deals with its re-compression after having looked for more appropriate dimensional references for information saving and future localization.
When you think about something that you have not thought about for a while, you may feel like the information is appearing out of nowhere, as if you were putting two and two together for the first time.
When you retrieve or become conscious of information or a concept, it seems as if the brain were continuing to retrieve elements associated with the stated information or concept at the same time. At certain times you can even visualize information and concepts like an explosion of data that are more and more precise in relation to what you were speaking or thinking about. Obviously, this retrieval depends on the length of time that has gone by since the last time that you thought about the specific subject and your necessity to continue thinking about it.
New computers, with their best techniques, keep becoming more and more similar to the brain. With their current processing speed they can start to automatically compress information that is not habitually used; before, decompression of a source of compressed information, if needed, would have been too slow.
Below we will analyse an illustrative example of elderly people who, often say the following sentences :
Of course, like in all complex processes, having little memory or not exercising specific sources of compressed information properly is positively correlated to Alzheimer.
3.4.2. Degradation of information storage
Another already known method in our culture is the degradation of information when it is compressed.
When computers compress an image in Bmp format to Jpg format, either no information is lost or a certain degree of information is lost, but nonetheless the new file has been significantly reduced.
Sensory memory, in particular, requires the actions of degradation in order to reduce the enormous amount of information that is received, such as when we think about music and songs, films, videos, etc.
3.4.3 Reconstruction of information
Corresponding to the phenomenon of the information degradation, there is also reconstruction of compressed or degraded information storage when required by the memory manager.
As we know, this phenomenon may convince a person of the existence of an act or a specific aspect because his/her memory says it exists when it actually does not. It may seem as if this person were lying, but, in fact, he/she is confused even though he/she may not be aware of this confusion.

Below we will analyse an illustrative example of elderly people who, often say the following sentences :
- I don't remember what I said five minutes ago.
- I don't remember what I ate yesterday.
- Strange, but I always remember perfectly when twenty years ago.
- Over time it becomes more difficult to compress more information that has already been compressed previously. This larger compression is considered necessary to free space in the brain memory given that throughout a person's life, it is assumed that he/she has used all available memory.
- Also, the gradual loss of an organism's vital energy with age, or any other problem, makes the compression mechanism less powerful.
- Logically, there comes a time when a part of the stored information needs to be erased in order to save news or a recent act.
- When in this situation, if someone decides to save new information, compressed information from during a lifetime will never be erased, unless the new information is very important. Normally information contained in the first or second superficial memory layers will be erased first.
- Another related aspect that we have already commented on is that older people do not need as much sleep.
Of course, like in all complex processes, having little memory or not exercising specific sources of compressed information properly is positively correlated to Alzheimer.
