El procesamiento del movimiento visual en primates no humanos (Macaca arctoides) es modulado por la atencion basada en objetos

Abstract

In the present study we examined the influence of object-based attention on the firing rate of neurons in the motion visual areas MTIMST. A macaque monkey was trained to selectively attend one of two superimposed surfaces defined by transparent motion and to discriminate its direction of motion. The results showed that object-based attention modulates the response of direction­ selective cells in these early visual areas. The presence of this attentional effect demonstrated that the object-based attention influences the early processing of visual motion.
