The body has been subject of psychoanalytic observation since Freud’s early works. Based on the impasses of contemporary clinic, this study tries to reflect upon the limits of representation and the acting-out on the body as an extreme effort to inscribe experiences of violence. Body marks such as cuts, fractures, burns and other scars come into play suggesting intense feelings that remain outside the associative circuit. These characteristics seem related to early experiences and to a clinical practice that focus on sensations and perceptions prior to language acquisition. The importance of the Other in the constitution of the psyche and of a body representation is contemplated. The paper`s main objective is to understand how the mother-infant body contact is responsible for giving the baby a sensation of body unification that, in turn, creates a favorable condition for the beginning of the psychical function of representation and elaboration of bodily sensations. Thus, a distinction is made between the hysteria s represented body and the body which is shown, site of excess, of the disconnected instinct that is outside the symbolic field.
