II.1. Concept of these brain functions

If we understand intelligence in broad terms, like the ability to link concepts or ideas, consider that a conclusion on the base of certain premises is no more than a link; we realize that we need concepts or ideas for operability or existence of intelligence, and the latter have to be provided by memory.

Similarly speaking, memory without a manager would no longer be memory in the strict sense of the word; it could not have the possibility of being information. In other words, the concept of memory implicitly includes a memory manager and vice versa. If computers' hard disks could not be read, they would be no more than a piece of useless junk.

Nonetheless, concepts can be differentiated somewhat artificially, emphasizing the ability to link or store information for intelligence and memory respectively. We say artificially because intelligence and memory can never be totally separated; we should try to keep this present so as not to lose perspective when dealing with certain lines of arguments.

II.2. How de brain works

Despite its relation, we are going to leave aside the problems that could arise from the study of the stances or theories on the existence of the soul-body (monism and dualism) and, although to a lesser extent, the mind-brain concepts (logical behaviorism - Wittgenstein, identity and functionalism) because they are more in the scope of theology and philosophy than in that of science.

Both intelligence and memory need physiological support; however, this is not to say that the support is the same for both. Without a doubt, cellular specialization exists and not just as far as intelligence or memory is concerned, but rather, insofar as both of their types or facets.

For example, there are cells specialized in searching for information in accordance with certain criteria, to analyze the relations according to the information that others have provided, etc. Specialization is even more evident in regards to memory; visual memory can be found in a different part of the brain than auditory or linguistic memory.

As we are all aware of, physiological endowment of particular ability or another can vary among individuals and their different functions and facets. But, at the same time, it would not make much sense if certain functions or mechanisms common to any type of memory or intelligence, appeared in one and not all the other types. In other words, genetic information of certain common functions of intelligence and memory are the same.

Computers also have similar elements with their corresponding specialties. There is a central chip, a possible mathematical processor, a graphic card, etc. Regarding memory, there is RAM memory, extended, expanded, hard drive, etc.

Regarding the subject of common functions, the example of computers clearly demonstrates what we are trying to say. The central processor can actually be used for many different purposes; two are, for example, as a mathematical calculator or to display graphics on the screen. This does not mean to say that more specific elements that improve general operation cannot exist, like a mathematical processor.

You should keep in mind that although a neuron is assigned to a particular function or is specialized, it can normally perform other types of functions. Specifically, it is worth mentioning that the simple act of closing our eyes allows us to immediately increase our auditory capacity and even our process of logic.

II.3. Complementariness of brain functions

A very important aspect related to these abilities is their complementariness. In the presentation of the goal of evolution coherence in the GTCEL, an example of normal complementariness of two variables is cited.

Nonetheless, we now find a special effect of complementariness beyond the normal effect. The greater our capacity of relating, the greater the efficiency of information provided by memory will be; but, at the same time, the information contributed will be greater from having a better memory manager. That is, intelligence operates twice, first as a memory manager, and second as an information analyzer.

Consequently, it may not be so exaggerated to think that the extent of the intellectual power, broadly speaking, is equal to the product of the capacities of intelligence and memory considered separately. That is, standardizing individual scales from 0 to 10, the total potential will be found in a scale of 0 to 100 and, like in all the complementary elements, the equilibrium will be more powerful; average values of both will give us a potential of 25, while relatively extreme values such as 2 and 8 will give us 16.

A computer's power is often measured both by the power of its central processor and the velocity of access to information and communication between its different parts; which affects the information manager's power in its phase of localization or recording.
