2.a) Concept of these brain functions

If we understand intelligence in broad terms, like the ability to link concepts or ideas, 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 has to be provided by memory.

Similarly speaking, memory without a manager would no longer be a 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 we could not read computers' hard disks, 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 separated entirely; we should try to keep this present so as not to lose perspective when dealing with specific lines of arguments.


2.b) How the brain works

Despite its relation, we are going to leave aside the problems that could arise when studying the positions or theories on the existence of the soul-body (monism and dualism) and, although in a smaller degree, the concepts mind-brain (logical behaviorism - Wittgenstein, identity, and functionalism) to be in the scope of theology and philosophy more than in science.

Both intelligence and memory need physiological support; however, this is not to say that both have the same. Without a doubt, cellular specialization exists for intelligence and memory functions.

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

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

Computers also have similar elements with their corresponding specialties. For example, there is a central chip, a possible mathematical processor, and a graphics card. Regarding memory, there is RAM, extended, expanded, and the hard drive.

On the subject of shared functions, the example of computers demonstrates what we are trying to say. The central processor can work for many different purposes; two are, for instance, as a mathematical calculator or to display graphics on the screen. Of course, more specific elements improving general operation can exist, like a mathematical processor.

We should keep in mind that although a neuron is assigned or specialized to a particular function, it can generally 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.


2.c) Complementariness of brain functions

A significant aspect related to these abilities is their complementariness. In the presentation of the coherence goal of evolution in the Conditional Evolution of Life book, we show an example of typical complementariness of two variables.

Nonetheless, we now find a special effect of complementariness beyond the usual effect. The more advanced our relational capacity, the higher the efficiency of information provided by memory will be; but, at the same time, the information contributed will be superior 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 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 the scale of 0 to 100. Even more, as in all complementary elements, equilibrium will be more powerful; average values of both will give us a potential of 25, while relatively extreme values such as two and eight 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.
