Descending Neurons of the Vertical Cell and Ocellar System (DNOVS)

Fig 1. Drosophila melanogaster. The lateral branch of this neuron is shown cobalt-coupled to the axon of a vertical motion-sensitive neuron (originating from the lobula plate) with which it shares gap junctions. The anteriorly directed dendritic branch receives chemical synapses from ocellar interneurons. Together, ocellar and vertical cells provide synergistic input to the DNOVS in its visual detection of head role.

Fig 2. A Texas red backfilled dendritic tree of a DNOVS neuron in the large fly Calliphora erythrocephala. Other red fluorescing cell bodies belong to other descending neurons that lie further ventrally and are not visible here. Nuclei of other neurons, intrinsic to the brain, are shown stained blue with bisbenzimide.
