ALT This image depicts visual processing in the fruit fly. Light enters the compound eye of the fly, causing hexagonally arranged photoreceptors to send electrical signals through a complex neural network, enabling the fly to detect motion. A team of researchers from HHMI’s Janelia Research Campus and the University of Tübingen used the fruit fly optic lobe connectome to build a detailed deep mechanistic network simulation of the fly visual system.
