This section was intended to treat the subject declared, but instead, it is just an evaluation of the problem. The reason is the inexistence of sufficient data on XZM models.
To make a local model on the normal human brain, we take some conditions from
MDT, as follows:
C1: The PSM must act to protect the being and to ensure the unconditional survival, forever, of that being. The PSM must also contain some models associated with the society in which the being lives. The PSM must not contain ordinary models.
C2: Any model of the brain must be stable (harmonic or logic).
C3: The whole structure of models must be stable. That is, any truth of any model must be accepted (or at least not rejected) by any other model of the brain.
Let's develop a little this local model.
The main condition of normality is that the person has to be accepted by the society. That is, the person has to integrate in that society. For a cannibal- type society, the person has to integrate in that society. Otherwise he will be rejected by the society. The limits or normality are, as we see, very broad.
For a democratic society of our time, some of the conditions of normality are "not to kill", "not to steal" and so on. Such models must be in the PSM and this goal is achieved by education since many generations.
Let's consider that a person makes a model to kill someone. If this model is blocked by PSM, that person can be considered as a normal one.
However, if a person makes a model to kill someone and, in some conditions, the PSM does not work properly, that model can be activated. Based on MDT, such a situation is a hardware problem and so, that person is not a normal one.
