Complex cells receive inputs from a number of simple cells. Their receptive field is therefore a summation and integration of the receptive fields of many input simple cells, although some input is directly received from the LGN. [4] The manner through which simple cells are able to make up complex cells is not fully understood.
Both simple and complex cells are linear operators and are seen as filters because they respond selectively to a large number of patterns. However, it has been claimed that the Gabor model does not conform to the anatomical structure of the visual system as it short-cuts the LGN and uses the 2D image as it is projected on the retina.

The prevailing theory of how simple and complex cells interact is that cells in the lateral geniculate nucleus stimulate simple cells, and simple cells in turn stimulate complex cells where then a combination of complex cells create depth perception. [1] [7] [10] Three different cell types exist: far cells, near cells, and tuned zero cells.
Simple cells have distinct subdivisions of excitatory and inhibitory regions. It is proposed that complex cells receive input from many simple cells, which explains why the complex cells have a slightly wider receptive field. [8] [9] There are possible biological advantages to the highly ordered structures of orientation columns.
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 are defined by the property of end-stopping, which is a decrease in firing strength with increasingly larger stimuli.
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...

English: Simple cells are orientation selective and formed from many centre-surroun receptive fields. Complex cells are sensitive to orientation, motion, and direction. Complex cells are sensitive to orientation, motion, and direction.
