Brain and vision, artwork
Brain and vision. Artwork of a mans head, brain and eyes seen from above, with arrows (white) showing the two streams hypothesis of visual processing. Sensory input from the left eye travels along the optic nerve to the rear and opposite side of the brain (with the reverse happening for the other eye). The two streams hypothesis states that after the information reaches the visual cortex (pink) in the occipital lobe, there are two paths it can follow. One is the dorsal stream (the where pathway) to the parietal lobe (green). The other is the ventral stream (the what pathway) along the temporal lobe (purple)

EDITORS COMMENTS
This artwork showcases the intricate connection between our brain and vision. From an aerial perspective, we observe a man's head with his brain and eyes clearly visible. The white arrows elegantly illustrate the two streams hypothesis of visual processing. As sensory input from each eye travels along the optic nerve, it intriguingly crosses over to the opposite side of the brain at the rear. This phenomenon is beautifully depicted in this print, emphasizing how our visual information is processed differently for each eye. Once this information reaches the visual cortex, represented by a vibrant pink area in the occipital lobe, it diverges into two distinct paths. The first path, known as the dorsal stream or "where pathway" leads to the parietal lobe (depicted in green). This stream enables us to perceive spatial awareness and locate objects within our environment. The second path, called the ventral stream or "what pathway" gracefully winds along the temporal lobe (shown in purple). This stream allows us to recognize and identify objects by their shape, color, and other visual characteristics. Through this mesmerizing artwork created by Science Photo Library, we gain a deeper understanding of how our brains process visual stimuli. It highlights both anatomical structures involved in vision processing as well as physiological functions that contribute to our perception of sight.
