[Proposal of a model of a mental system based on mental functions]

Based on the mental functions according to classical physiological criteria, the authors propose an information management system with heuristical value for Psychiatry. This system assumes that information will be received by the sensoperceptual area, being analyzed within both the cognitive and affective areas later on, the analysis output thus taking place through the psychomotor area. Such a system allows a theoretical structure -correlating some aspects of Neurosciences with psychiatric clinical events, to be elaborated. Furthermore, such a system allows mental disorders to be understood as disturbances in the information processing the nervous tissue performs.
