Spike Burst Coding of Translatory Optic Flow and Depth from Motion in the Fly Visual System (Current Biology)

Longden et al. report novel optic flow-processing neurons in the fly with motion receptive fields matched to translatory optic flow. One of these cells, VT1, encodes properties of the moving visual scene in spike bursts, such that depth from motion modulates the rate of spike bursts and not the rate of single action potentials.
