The C3-condition states that the whole structure of models must be harmonic/logic. This condition is not easy to meet. First of all, there is a limited capacity to refresh the whole structure of models. The refresh capacity for some persons could be under the requirements. Such persons could evolve to a form of schizophrenia. Let's consider now a person-A, who meets the C3 criterium. At one moment, an important model becomes useless (for instance, an important person B disappears from the life of A). In such case, person-A has to refresh the whole structure of models. This task could exceed the technical capacity of refresh (mainly for older persons). It the refresh capacity is exceeded, one possibility is to make shielding models. If a person has too many shielding models, such a person cannot be considered as a normal person. Such persons can be detected, e.g. due to the fact that they don't want, or they cannot discuss about some subjects. XZM models are not taken into account because of the lack of enough data about them. XZMs can explain the somnambulistic-effect, multiple personalities or even some nonsense crimes. There are killers who don't know why they kill other people. Many of them seem to be normal persons, as their friends can confirm and also they can be integrated in society. XZMs can be an explanation for their crimes. Indeed, an XZM is a model which is out of the control of the normal structure of models. Such models can become active-models in some situations (due to the hardware problems of that brain). The killer is so "remotely-controlled" by the XZM. Such killers cannot be detected by a lie detector. The explanation is the fact that there is no normal model that makes the crime and so, there is no reason to pretend or hide something. As I said, this section is just for evaluation. As new data will be obtained in association with XZMs, the section will be developed. THE ABSTRACT OF THE FUNCTIONAL FACILITIES OF A BRAIN Let's make an abstract about all the functional facilities of a human brain. Almost all the facilities, which are not related with symbolic-models, are the same for animals. BF1: To make models associated or not with a section of the external reality BF2: To refresh, on and on, the M-models by prediction and comparison with IR, so that M-models reflect better and better the dynamic external reality. BF3: The continuous self-refreshing of some ZM coupled with M-models. The goal is that these ZM-models reflect better and better the external reality. For this, ZM must take into account any other ZM-model of the brain as well. BF4: To simulate, continuously, the possible evolution of the associated external reality, even when a ZM is not connected to M-models.
