from photoreceptors, which only respond to changes in luminance, could be used to compute motion. Each photoreceptor, responded to a change in luminance at a given location in visual space. Comparison of the phase shift of activity in adjacent cells indicated the direction of movement from one neuron's receptive field to the other. This model of micro-circuitry became known as a Reichardt detector. Whilst there is experimental evidence consistent with the hypothetical behaviour of a Reichardt detector, the corresponding circuitry has not yet been found. In honor of Reichardt's pioneering work, the Tübingen cluster of excellence Werner Reichardt Centre for Integrative Neuroscience (CIN; founded 2007/2008) was named after him.
