As any scientific theory, it is a symbolic model. Any symbolic model is based on a limited number of basic terms and a limited number of basic relations between the basic terms. For the basic terms and only for them, there are accepted descriptive definitions. All the others terms are generated by the model, together with their normal definitions. These definitions are generated by the model by logical and mathematical procedures. These are the basic characteristics of any scientific theory and so, I follow the procedures described above, to make a theory on the basic hardware functions of the brain. This theory is in a total opposition with all the actual sciences associated with the functions of the brain. The present sciences, associated with the functions of the brain, are not based on a single fundamental model. In this way, as my theory will be accepted, all what it was already written in the actual sciences associated with the functions of the brain, have to be re-written or forgotten. This attempt of total revolution is necessary because the actual sciences on the brain don't use normal definitions of the terms; there are only descriptions associated with them. Because the definitions of the terms are not generated by a single fundamental model, the logical corelation between them is not possible. So, the actual sciences associated with the brain cannot evolve to become positive science anymore. In psychology, for instance, about any scientist has his/her own list of descriptive definition associated with the terms used by him/her. In this way, it is not possible to make a logical structure to integrate all the terms used in that field. So, the psychology, for instance, is not a positive science. Another example: Let's consider a classical positive science, as Newton's Mechanics is. In this symbolic model, all terms have exactly the same definition for all the scientists. These definition are not changed since 340 years ago when they were generated by the symbolic model of Mechanics. For instance, the term "speed" is defined as v=s/t. That is, "speed" means that the "space" is divided by "time". This definition is a normal definition generated by the symbolic model of Mechanics not a descriptive definition. Let's suppose now that a symbolic model associated with the basic hardware function of the brain is already created or it will be created. The first consequence is that all the terms used in association with the functions of the brain will be generated by the model by logical and mathematical procedures, together with their normal definitions. There is no reason to suppose that any descriptive definition which is already used in the present sciences of the brain will be compatible with the definitions generated by that symbolic model. So, all what is already created in the present sciences associated with the brain has to be re-written or forgotten.
