title: Four to Foxtrot: How Visual Motion Is Computed in the Fly Brain.
abstract: In this issue of Neuron, Serbe et al. (2016) use cell-type-specific genetic tools to record and manipulate all major inputs to directionally selective neurons in Drosophila. Their results localize the site of motion computation and reveal unexpected complexity of temporal tuning in the underlying neural circuit.
