Simple integration of fast excitation and offset, delayed inhibition computes directional selectivity in <i>Drosophila</i> , Published online: 08 January 2018; doi:10.1038/s41593-017-0046-4

In the Drosophila visual system, T4 is the first cell type in the ON pathway to exhibit directionally selective signals. This directional selectivity originates from simple integration of spatially offset fast excitatory and slow inhibitory inputs.
