  2. Visual cortex - Wikipedia

    en.wikipedia.org/wiki/Visual_cortex

    The area of the visual cortex that receives the sensory input from the lateral geniculate nucleus is the primary visual cortex, also known as visual area 1 , Brodmann area 17, or the striate cortex. The extrastriate areas consist of visual areas 2, 3, 4, and 5 (also known as V2, V3, V4, and V5, or Brodmann area 18 and all Brodmann area 19 ).

  3. Visual neuroscience - Wikipedia

    en.wikipedia.org/wiki/Visual_neuroscience

    Visual neuroscience is a branch of neuroscience that focuses on the visual system of the human body, mainly located in the brain's visual cortex. The main goal of visual neuroscience is to understand how neural activity results in visual perception , as well as behaviors dependent on vision.

  4. Two-streams hypothesis - Wikipedia

    en.wikipedia.org/wiki/Two-streams_hypothesis

    Goodale and Milner [2] amassed an array of anatomical, neuropsychological, electrophysiological, and behavioural evidence for their model. According to their data, the ventral 'perceptual' stream computes a detailed map of the world from visual input, which can then be used for cognitive operations, and the dorsal 'action' stream transforms incoming visual information to the requisite ...

  5. Visual processing - Wikipedia

    en.wikipedia.org/wiki/Visual_processing

    The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...

  6. Visual system - Wikipedia

    en.wikipedia.org/wiki/Visual_system

    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.

  7. Human visual system model - Wikipedia

    en.wikipedia.org/wiki/Human_visual_system_model

    A human visual system model (HVS model) is used by image processing, video processing and computer vision experts to deal with biological and psychological processes that are not yet fully understood. Such a model is used to simplify the behaviors of what is a very complex system. As our knowledge of the true visual system improves, the model ...

  9. Visual field - Wikipedia

    en.wikipedia.org/wiki/Visual_field

    The visual field is "that portion of space in which objects are visible at the same moment during steady fixation of the gaze in one direction"; [1] in ophthalmology and neurology the emphasis is mostly on the structure inside the visual field and it is then considered “the field of functional capacity obtained and recorded by means of perimetry”.
