Beyond the resolution limit: Modeling the dipteran visual system

The common housefly has realized a visual system that can detect stimulus displacements with higher resolution than those predicted by the packing of detectors within Its retinal array. Its neural substrate extracts and encodes this Information directly from the visual scene. This substrate utilizes detectors whose size Is near the diffraction limit and yet achieves ten times better resolution than would be expected from the spacing of such coarse detectors. The functional basis of this substrate and Its significance to hyperaculty has been modeled and simulated.
