Since the results of the integrative activity are obviously real, the corresponding mathematical transformation should have a physical basis. But nothing that we now know in Physics can offer the integrative property that we are searching, or at least a modality of constructing such an integrative property. But neither could we accept it outside Physics and hence the mental field should represent, or be constructed with, a physical reality, although we consider it as a mathematical concept. But what kind of physical reality ? The phenomenon we are dealing with represents the surest transition towards continuum. Hence a continuous physical reality should be utilized or created; however this cannot be done in our discontinuous universe, hence we should think about an intrinsic space (or coordinate) of the continuum, that in fact is no longer a space, but could be something that we called orthoexistence.
No doubt that the mental wave (field) should have a physical nature entirely different from what we know, its integrative role providing a continuous information, matching a continuous information. The mental field could be a material substance with an informational character, not only for the continuous geometric information, for discontinuous existence forms, but also for continuous psychological information, for integrating the machine-states from its emotional and rational domains. The mental field could be an orthoexistent field. Orthoexistence, in itself, appears informationally statical; via its coupling with the subjects it can become dynamical. We have seen that we can search an informational root for all things, including elementary particles. Hence it does not surprise us that organizations as complex as the animal, the man and their nervous systems, have at their basis a genetic information, thus reflecting the deep informational properties of the matter.

Human body and its nervous system are build up starting from the genetic information contained in the embryonic cell. In the last years much work has been done regarding the way the nervous system is built up, the way neuronic circuity is constructed inside the growing organism⁹¹. The current point of view is that of genetic programming. Otherwise, how could it be possible for millions of neurons to grow and to find their way up to the precise point in which they have to interconnect? One should accept a specific role for the nervous fibers. "Although the cells may be identical, their addresses and their connections are far from being so. It is this which makes the question of their specificity that much more significant"⁹².
The properties of mutual recognition of the neurons, "the connective organization of the nervous system down to the level of synapses is subject to the all powerful influence of the genes"⁹³. The genetic codes do not contain all the details of the nervous circuitry, but only the general pattern; the embryo cell is considered a finite automaton, in which the possible subsequent states are determined by the previous states and also by the momentary activity: "One way or the other, the activity state of the neurons network contributes to the final connectivity pattern"⁹⁴. This generates an unique property to the brain computer, i.e. that of modifying, within limits, its own circuitry, corresponding to the signals going through it⁹⁵. For this reason Steven Rose considers that the brain has the possibility of modifying its structure and functionality as a response toexternal circumstances⁹⁶. This modification is expected to appear "... in terms of a modification of biochemistry, of cellular architecture and connectivity, of the electrical responses of the brain"⁹⁷. Sometimes one says⁹⁸:

"The brain is like a muscle. Use it and it will grow".
