Consciousness around the time of saccadic eye movements

  • Bruce Bridgeman (a1)

Abstract

During saccadic eye movements, the job of the nervous system is not to perceive a change in stimulation from the receptors, but to prevent a change from reaching consciousness. These movements occupy an intermediate range between actions that are almost always conscious, such as finger movements, and those that are never conscious, such as the smooth-muscle actions of the digestive system. Consciousness in this context requires attention to the consequences of an action.
