  • Perception
  • This crossing is an adaptive feature of frontally oriented eyes, found mostly in predatory animals requiring precise visual depth perception. (wikipedia.org)
  • Tom Norman Cornsweet (April 29, 1929 - November 11, 2017) was an American experimental psychologist known for his pioneering work in visual perception, especially the effect that bears his name, and in the development of ophthalmic instrumentation. (wikipedia.org)
  • 1963. Visual Perception. (wikipedia.org)
  • Goodale's research focuses on the neural substrates of visual perception and visuomotor control. (wikipedia.org)
  • Goodale's early work in the 1980s, in which he demonstrated that visual perception is functionally independent of the visual control of action, laid the foundation for the 'duplex' account of high-level vision which he developed later, together with his long-time colleague, David Milner (originally based at the University of St. Andrews but now at Durham University). (wikipedia.org)
  • According to Goodale and Milner's two visual systems model, visual perception uses relative metrics and scene-based frames of reference whereas the visual control of action uses real-world metrics and egocentric frames of reference. (wikipedia.org)
  • Saccadic masking, also known as (visual) saccadic suppression, is the phenomenon in visual perception where the brain selectively blocks visual processing during eye movements in such a way that neither the motion of the eye (and subsequent motion blur of the image) nor the gap in visual perception is noticeable to the viewer. (wikipedia.org)
  • Medial
  • The cells with visual receptive fields also fire with head-centered reference frames but possibly also with eye-centered coordinates The medial intraparietal (MIP) area neurons encode the location of a reach target in nose-centered coordinates. (wikipedia.org)
  • However, the central point of the theory was exactly to obtain a faithful visual map with the medial field projecting to the medial sides of the visual cortex. (wikipedia.org)
  • streams
  • In 1982 Ungerleider and Mishkin distinguished the dorsal and ventral streams, as processing spatial and visual features respectively, from their lesion studies of monkeys - proposing the original where vs what distinction. (wikipedia.org)
  • intracranial
  • A chapter is devoted to the meticulous presentation of imaging anatomy of the orbit and intracranial visual pathway. (springer.com)
  • Another chapter gives an overview of visual system impairment in the pediatric age group.The special part provides detailed descriptions of the symptoms and clinical and imaging findings in individual patients with orbital and intracranial pathologies. (springer.com)
  • in 2014, stimulation of the region via intracranial electrodes yields intense topographical visual hallucinations of places and situations. (wikipedia.org)
  • Lateral
  • The transfer functions of Lateral Geniculate Nucleus and of Visual Cortex I have been determined under conditions of steady state flickering illumination at fixed intensity. (dtic.mil)
  • The lateral intraparietal sulcus (LIP) contains neurons that produce enhanced activation when attention is moved onto the stimulus or the animal saccades towards a visual stimulus, and the ventral intraparietal sulcus (VIP) where visual and somatosensory information are integrated. (wikipedia.org)
  • system
  • This is one of the first books to deal with imaging of pathology of the entire visual system. (springer.com)
  • The results of immunohistochemical experiments using monoclonal antibody 8D9 to study the development of the chick visual system are consistent with the 8D9 antigen functioning in axon fasciculation. (jneurosci.org)
  • These folia also receive visual input from the tectofugal system via pontine nuclei. (nih.gov)
  • The optic tract (from the Latin tractus opticus) is a part of the visual system in the brain. (wikipedia.org)
  • OKN can be used as a crude assessment of the visual system[citation needed], particularly in infants. (wikipedia.org)
  • The cells are part of the visual system. (wikipedia.org)
  • 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 egocentric (head-centered) coordinate system for skilled motor planning. (wikipedia.org)
  • Imaging
  • Further chapters are devoted to neuroophthalmology and functional imaging of the visual pathway with presentation of the latest knowledge on the indication, technique and results of functional MR imaging. (springer.com)
  • temporal
  • Cells in the M pathway have the ability to detect high temporal frequencies and can thus detect quick changes in the position of an object. (wikipedia.org)
  • Neural
  • A major theme underlying Davida Teller's research was the nature of the relationship between visual phenomena and their neural underpinnings. (wikipedia.org)
  • Cortical
  • Cortical functions of the parietal lobe are: Two point discrimination through touch alone without other sensory input (i.e., visual) Graphesthesia - recognizing writing on skin by touch alone Touch localization (bilateral simultaneous stimulation) The parietal lobe plays important roles in integrating sensory information from various parts of the body, knowledge of numbers and their relations, and in the manipulation of objects. (wikipedia.org)
  • Vision
  • The resulting hierarchical representation of visual scenes, including the representation of hierarchical binding relations between lower and higher level visual features, is consistent with the hierarchical phenomenology of primate vision. (bristol.ac.uk)
  • patients
  • Our findings represent a step forward in the scientific understanding of visual deficits associated with albinism and are likely to aid clinicians in the management of affected patients. (le.ac.uk)
  • psychophysical
  • However, an unresolved issue is the extent to which the FPL technique (or any psychophysical technique, for that matter) measures the best possible visual capacity of an infant, animal, or patient. (wikipedia.org)
  • Children
  • In the early 1970s, following the birth of her children, Davida Teller began her studies of infant visual development that were to be the main topic of her research for the remainder of her career. (wikipedia.org)
  • Search
  • Due to this contrast information, M cells are essential for detecting changes in luminance, and performing visual search tasks and detecting edges. (wikipedia.org)
