The basic principle of motion detection by fibers of the optic lobes of flies were studied with a pair of small spots and a variety of paired intensity variations. These show that the process of correlation of adjacent field regions to detect motion is confined to a small area. The presence of small field units with small field adjacent inhibition in the system was detected. The optimum spot spacing for maximum reactions corresponded to the facet spacings. Selective motion detection responses from minimum information consisting of evaluating the difference between the spot intensities and the rate of change of the trailing spot relative to the motion direction was shown. However, additional properties best determined by white-noise experiments designed from this study were found.
