Lobula plate and ocellar interneurons converge onto a cluster of descending neurons leading to neck and leg motor neuropil in Calliphora erythrocephala

In the fly, C. erythrocephala , a cluster of three Y-shaped descending neurons (DNOVS 1-3) receives ocellar interneuron and vertical cell (VS4-9) terminals. Synaptic connections to one of them (DNOVS 1) are described. In addition, three types of small lobula plate vertical cell (sVS) and one type of...

Description
Summary:In the fly, C. erythrocephala , a cluster of three Y-shaped descending neurons (DNOVS 1-3) receives ocellar interneuron and vertical cell (VS4-9) terminals. Synaptic connections to one of them (DNOVS 1) are described. In addition, three types of small lobula plate vertical cell (sVS) and one type of contralateral horizontal neuron (Hc) terminate at DNOVS 1, as do two forms of ascending neurons derived from thoracic ganglia. A contralateral neuron, with terminals in the opposite lobula plate, arises at the DNOVS cluster and is thought to provide heterolateral interaction between the VS4-9 output of one side to the VS4-9 dendrites of the other.
