<Li> Finally, if we were to assume that all of the aforementioned were not true, and that one cortical cell could indeed record one specific detail, then based on the fact that cells die we would need to have the same information contained in a back - up cell (similar to how you back up files on your computer). If there was no back - up, then the death of a single cell would result in the complete loss of ability to recognize that specific object or feature . </Li> <P> The reasonable alternative to feature detectors would be that cortical cells work as a network . Hence the recognition of a face results not from the feedback of one individual cell but rather from a large number of cells . One group of cells would be specifically inclined to excitatory responses for a given feature such as height, while another would be sensitive to movement . This has been partially proven, as three types of cells simple, complex and hypercomplex have been identified in the receptive fields of cells in the cortex . </P>

Where are feature detectors located in the eye
