WebbReceptive fields of cells in the visual cortex are larger and have more-complex stimulus requirements than retinal ganglion cells or lateral geniculate nucleus cells. Hubel and Wiesel (e.g., Hubel, 1963; Hubel-Wiesel 1959) classified receptive fields of cells in the visual cortex into simple cells, complex cells, and hypercomplex cells.

Webb1 nov. 2024 · In traditional classifications, simple cells have segregated ON/OFF sub-regions of receptive fields and generate highly modulated sinusoidal response ( F 1 / F 0 > 1) to drifting gratings stimuli, while complex cells have largely overlapping ON/OFF sub-regions and generate weak modulation of response ( F 1 / F 0 < 1, Fig. 1 a) ( De Valois et … Webb1 sep. 2007 · Here we classify simple and complex cells based on the ratio between the first Fourier coefficient (F 1) and mean spiking responses (F 0) to moving sine-wave gratings (Skottun et al. 1991). F 1 /F 0 ratios >1 or <1 indicate simple or complex cells, respectively. We classified a cell as simple or complex based on its response to 100% … イオン鴻池営業時間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.
