Simple complex and hypercomplex cells

WebbThese cells were discovered by Torsten Wiesel and David Hubel in the late 1950s. Hubel and Wiesel named these cells "simple," as opposed to "complex cell", because they … Webb1 The organization of the visual cortex was studied with a technique that allows one to determine the physiology and morphology of individual cells Micro-electrodes filled with the fluorescent dye Procion yellow were used to record intracellularly from cells in area 17 of the cat The visual receptive field of each neurone was classified as simple, complex, …

Simple Cells in the Visual Cortex - Vivid Vision

WebbThe visual cortex was studied in the mouse (C57 Black/6J strain) by recording from single units, and a topographic map of the visual field was constructed. Forty‐five percent of … Hypercomplex cells were originally characterized as the superordinate class of visual processing cells above complex and simple cells. Whereas complex cells were sensitive to moving stimuli of specific orientations that travel in a specific direction, simple cells only responded to properly oriented linear stimuli. Visa mer A hypercomplex cell (currently called an end-stopped cell) is a type of visual processing neuron in the mammalian cerebral cortex. Initially discovered by David Hubel and Torsten Wiesel in 1965, hypercomplex cells … Visa mer Shortly after Hubel and Wiesel included hypercomplexity into their version of the visual processing hierarchy, the notion of a class of hypercomplex cells was contended. In 1968, Geoffrey Henry and Bogdan Dreher discovered simple and complex cells in … Visa mer Knowledge of cortical function was relatively limited by the 1950s. However, towards the end of the decade, the platform for … Visa mer Although end-stopped cells are a phenomenon of the mammalian visual cortex, there have been discoveries of cells exhibiting end-stopping properties within a variety of other Visa mer

WebbThe effect of attention during adaptation on subsequent negative afterimages was examined. One of 2 overlapped outline figures was attended during a 7-10-s adaptation period.
