Before revision:  This question depends on the complexity of the visual input, the set of transforms applied to this multivariate input, and the noise of the sensors in the considered layer . Separate subsystems (e.g. opponent channels, spatial filters, nonlinearities of the texture sensors) have been suggested to URLanized for optimal information transmission.
