Neurological evidence has shown that brain damages canselectively impair the ability to discriminate between objectsbelonging to others and those that we feel are our own. Despitethe ubiquity and relevance of this sense of object ownership forour life, the underlying cognitive mechanisms are still poorlyunderstood. Here we ask whether psychological ownership ofan object can be based on its incorporation in one’s body image.To explore this possibility with healthy participants, weemployed a modified version of the rubber hand illusion inwhich both the participant and the rubber hand wore a ring. Weused the self-prioritization effect in a perceptual matching taskas an indirect measure of the sense of (dis)ownership overobjects. Results indicate that undermining the bodily self hascascade effects on the representation of owned objects, at leastfor those associated with the body for a long time.

Exteroceptive and interoceptive signals shape and sustain the bodily self-awareness. The existence of a set of brain areas, supporting the integration of information coming from the inside and the outside of the body in building the sense of bodily self-awareness has been postulated, yet the evidence remains limited, a matter of discussion never assessed quantitatively. With the aim of unrevealing where in the brain interoceptive and exteroceptive signals may converge, we performed a meta-analysis on imaging studies of the sense of body ownership, modulated by external visuotactile stimulation, and studies on interoception, which involves the self-awareness for internal bodily sensations. Using a multilevel kernel density analysis, we found that processing of stimuli of the two domains converges primarily in the supramarginal gyrus bilaterally. Furthermore, we found a right-lateralized set of areas, including the precentral and postcentral, and superior temporal gyri. We discuss these results and propose this set of areas as ideal candidates to match multiple body-related signals contributing to the creation of a multidimensional representation of the bodily self.

La creciente literatura sobre el cuerpo, la acción y la primera persona nos deja con un panorama de considerable complejidad que hace visible la necesidad de proveer –o empezar a proveer– aproximaciones unificadoras en la intersección de diferentes nociones y áreas de investigación. Los artículos que constituyen este volumen pueden verse como asumiendo este gran reto en relación con una serie de temas específicos, y girando en torno a la idea de que la acción y elementos básicos del análisis de la acción están llamados a desempeñar un papel crucial en la caracterización del nexo fundamental entre el cuerpo y la persona.

L’auteur qui a une double pratique: de psychanalyste et de sculpteur, interroge l’objet de la création dans la sculpture et l’objet «symptomatique» de l’Art-thérapie, pour dégager la tension entre l’objet intrapsychique et l’objet en «dehors», et faire apparaître une circulation symbolique entre les deux. Rodin et Picasso sont convoqués pour, montrer comment l’œuvre de la sculpture est «incarnée», comment le corps subjectif est le socle de la «figuration plastique». Les «figurations du tactile» et l’«extension de l’appareil psychique» permettront d’énoncer la notion de plasticité psychique, esquissée dans la pensée freudienne, mais définie par l’auteur comme un axe central de la psychanalyse contemporaine., Psychic Plasticity - ‘Cubic’ Figuration Reaching Out towards the Object The author of this article is both psychoanalyst and sculptor, and in this dual role examines the object of creation in sculpture and the ‘symptomatic’object in Art Therapy. This sheds light on the tension established between the intra-psychic object and the ‘outside’ object and shows how a symbolic current circulates between the two. The work of Rodin and Picasso illustrates how a work of sculpture becomes ‘incarnate’, how the subjective body is the basis of all ‘plastic figuration.’ ‘Tactile figurations’ and the ‘extension of psychic apparatus’prepare for an exploration of the notion of psychic plasticity, already prepared for in Freud’s thinking but defined here by the author as an essential keystone of contemporary psychoanalysis.
