De la représentation cérébrale spatio-temporellement distribuée à la capture ici et maintenant d'un objet visuel en mouvement

Abstract : Over the course of their phylogenetic and ontogenetic evolution, the animals were faced with the need to manage an environment which is not composed of static objects. In their world, the most significant events often occur when things (animal or not, predator, prey, congeners or other) move or when themselves they move. In front of this dynamism, the animals exhibit the ability to pursue and catch a prey, to avoid a predator, in flight for some of them. How are such performances, spatio-temporally accurate, possible? Should we believe that the functioning of the brain sets general frames (such as space and time) and principles similar to those used by the Newtonian mechanics for describing the motion of a rigid body? In this chapter, we expose how the neurophysiological study of saccades toward a moving visual target permits to bring some significant answers to these questions, and in passing, to expose doubts about the suggestions that the notion of space or that the laws of mechanics could have any physiological equivalent. It would be wiser to consider that such notions are merely concepts, notions useful only for thinking about things. A new line of research is proposed in order to identify the neurophysiological processes underlying what we call the visuomotor presence, i.e., this ability to produce behaviors which are accurate here and now.
