Spatiotemporal filtering, for a disk of diameter 11° moving from left to right.
A: Pattern of light incident on the retina at a particular moment of time. B: After spatial filtering through a Gaussian with a standard deviation of 0.7°, representing the acceptance angle of foveal mantis ommatidia. C: The resulting neural input, after temporal filtering and squaring. There is activity only at the leading and trailing edges of the disk, where the retinal stimulus is changing.
