title: When Visual Circuits Collide: Motion Processing in the Brain.
abstract: How is sensory information transformed by each station of a synaptic circuit as it flows progressively deeper into the brain? In this issue of Cell, Mauss et al. describe a set of connections in the fly brain that combines opposing directional signals, and they hypothesize that this motif limits global motion noise as the fly moves through space.
