Abstract :
Digital signal processing techniques are applied to electrophysiological data from the fly Sarcophaga in studying the functional significance of the clock-spike and eye muscle (CSEM) system associated with the fly´s compound eyes. It is shown that the predictions of a spatial-temporal filtering model confirm that the CSEM system performs target tracking which greatly enhances the signal-to-noise ratio at the output of each elementary motion detector
