  2. Visual system - Wikipedia

    en.wikipedia.org/wiki/Visual_system

    The visual system performs a number of complex tasks based on the image forming functionality of the eye, including the formation of monocular images, the neural mechanisms underlying stereopsis and assessment of distances to (depth perception) and between objects, motion perception, pattern recognition, accurate motor coordination under visual ...

  3. Visual pathway lesions - Wikipedia

    en.wikipedia.org/wiki/Visual_pathway_lesions

    The visual pathway consists of structures that carry visual information from the retina to the brain.Lesions in that pathway cause a variety of visual field defects. In the visual system of human eye, the visual information processed by retinal photoreceptor cells travel in the following way:

  4. 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.

  5. Two-streams hypothesis - Wikipedia

    en.wikipedia.org/wiki/Two-streams_hypothesis

    Thus the emerging perspective within neuropsychology and neurophysiology is that, whilst a two-systems framework was a necessary advance to stimulate study of the highly complex and differentiated functions of the two neural pathways; the reality is more likely to involve considerable interaction between vision-for-action and vision-for-perception.

  6. Neural pathway - Wikipedia

    en.wikipedia.org/wiki/Neural_pathway

    A neural pathway connects one part of the nervous system to another using bundles of axons called tracts. The optic tract that extends from the optic nerve is an example of a neural pathway because it connects the eye to the brain; additional pathways within the brain connect to the visual cortex.

  7. Visual acuity - Wikipedia

    en.wikipedia.org/wiki/Visual_acuity

    Neural factors include the health and functioning of the retina, of the neural pathways to the brain, and of the interpretative faculty of the brain. [ 1 ] The most commonly referred-to visual acuity is distance acuity or far acuity (e.g., "20/20 vision"), which describes someone's ability to recognize small details at a far distance.

  8. Binocular neurons - Wikipedia

    en.wikipedia.org/wiki/Binocular_neurons

    Binocular neurons in the dorsal and ventral pathways combine to create depth perception, however, the two pathways perform differ in the type of stereo computation they perform. [7] The dorsal pathway generally performs a cross-correlation based upon the region of the different retinal images, while the ventral pathway fixes the multiple ...

  9. Magnocellular cell - Wikipedia

    en.wikipedia.org/wiki/Magnocellular_cell

    Visual representation of the parvocellular and magnocellular pathways. From the LGN, the M pathway continues by sending information to the interblob regions of the 4Cα layer of the V1 region of the visual cortex, also called the "striate cortex". [6] Other cells in the striate are more influenced from signaling from P cells and yet others from ...
