A atualidade do projeto freudiano de 1895

The purpose of this article is to explore the concept of memory and "psychic apparatus" as described by Sigmund Freud in his "Project for a scientific psychology", 1895. The "apparatus" is a neuron network capable of transmiting and transforming energy that feeds the system, being a model of explanation of normal psychic ac- tivity function, as well as its possible disturbances. We consider that, in the apparatus dynamic, ideas precursory of current concepts in neuroscience and cognitive science are present.
