The motion detection circuit suggested by a connectome reconstructed from the Drosophila brain [39]. (a) Visualization of 379 neurons in the connectome, which is a part of the optical lobe; (b) the offset (black arrow) of the receptive fields computed from the circuit, which involves L1 (yellow), Tm3 (magenta), Mi1 (cyan), and T4 neurons, suggests a potential implementation of (c) the Hassenstein-Reichardt model.
