There are ganglion cells in the pigeon retina that respond selectively, some to any edge moving in a particcular direction only, others to any vertically moving horizontal edge. This selective response to a specific stimulus arises from the selective sensitivity of each neuron to a particular spatiotemporal configuration in its afferent influences, and is independent of specific pathways.
