The traditional thinking was that the brain somehow ‘sees’ the image, but increasing evidence suggests that most of vision is the result of driven tests that are ordered up to serve a cognitive agenda, so much so that even interrupts may be modulated by an agenda-driven context. Much of this change of perspective has been driven by the primate visual system’s retinal organization, which has a pronounced high-resolution foveal region at the center of a low-resolution periphery. This architecture sends a very compressed coded version of the image to the Thalamus, which uses extensive cortical feedback for its interpretation. The foveal architecture also demands that a collection high-speed eye movements are used to stabilize gaze on important targets. Studies of such movements show that they are exquisitely programmed to facilitate the extraction of task-centric information from the image quickly.
