Document Summary
Input will alternate between left eye and right eye, some are binocular. Entire chunk is processing one area in the visual field. Each art of visual field is represented by a chunk like this. Visual cortex: signal is elaborated = line segments. Depending on how 3 neurons combine: can create line segments visual receptive field. Processing of this visual signal explodes in visual cortex. Dorsal stream heading up to parietal and motor: carrying magnocellular, visual receptor field, big neurons, big changes of envormnet, not high acuity, not colour. Ventral: high acuity, little line segment details, faces, colour vision, small receptor fields, for perception. Primary visual cortex (area 17, striate cortex, v1) projects to a collection of more than. Coloured areas are involves in processing visual stimuli. About half the areas of the cortex are coloured in and involved with visual processing. This highlights how important visual processing is. Hundreds of areas of visual processing interconnected.
