Cognitive processes can be considered, in the first instance, as self-organizing and complex processes characterized by a continuous emergence of new categorization forms and by self- referentiality. In order to understand the inner mechanisms of this kind of processes we have to outline a theory of more and more sophisticated forms of organization. We need, for instance, to define new measures of meaningful complexity, new architectures of semantic neural networks, etc. In particular, we have to take into consideration the genetic and "genealogical" aspects that characterize the inner development of cognitive symbolic structures. However, cognition is not only a self-organizing process. It is also a co-operative and coupled process. If we consider the external environment as a complex, multiple and stratified Source which interacts with the nervous system, we can easily realize that the cognitive activities devoted to the "intelligent" search for the depth information living in the Source, may determine the same change of the complexity conditions according to which the Source progressively expresses its "wild" action. In this sense, simulation models are not neutral or purely speculative. True cognition appears to be necessarily connected with successful forms of reading, those forms that permit a specific coherent unfolding of the deep information content of the Source. Therefore, the simulation models, if valid, materialize as "creative" channels, i.e., as autonomous functional systems, as the same roots of a new possible development of the entire system represented by brain and its Reality.
