Hypercomplex cell
From Wikipedia, the free encyclopedia
Hubel and Wiesel[1] named cells in the visual cortex that exhibit end stopping properties Hypercomplex cells, but later research has found them to be subclasses of the simple and complex cells. End stopping is when a cell's response increases as a stimulus, for example a bar, expands to fill the receptive field, and then responds less when the stimulus exceeds the size of the receptive field There are three classes of cells in V1: Simple cells: “line detectors “and “edge detectors “ Complex cells detect orientation Hypercomplex cells detect length
