The visual system is the physiological basis of visual perception (the ability to detect and process light). The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
The visual system is the part of the nervous system which allows organisms to see. It interprets the information from visible light to build a representation of the world surrounding the body. The visual system has the complex task of (re)constructing a three dimensional world from a two dimensional projection of that world.
The visual cortex of the brain is the area of the cerebral cortex that processes visual information. It is located in the occipital lobe. Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.
Dec 19, 2022 · The visual system consists of two primary parallel pathways: an optic pathway and a pupillary reflex pathway. [2] [3] Optic Pathway. The optic pathway begins in the retina, which is a complex structure made up of ten different layers. Each layer serves a distinct function.
Psychology. Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment.
The Human Visual System. The visual system includes both the eyes and the brain.Light enters your eye where it hits the retina, which triggers light receptors to send electrical signals through your optic nerve, which travel to the back of your brain where the first stages of visual perception take place.
Jul 27, 2023 · The visual pathway refers to the anatomical structures responsible for the conversion of light energy into electrical action potentials that can be interpreted by the brain. It begins at the retina and terminates at the primary visual cortex (with several intercortical tracts).
