part of expresses receives synaptic input in region sends synaptic output to region sends synaptic output to cell Rh3 medulla layer M3 photoreceptor cell R7 distal medullary amacrine neuron Dm8a pale optic column pale ommatidium photoreceptor cell R7 of pale ommatidium pR7 Photoreceptor cell R7 that is part of a pale ommatidium and expresses Rhodopsin 3 (Wernet and Desplan, 2004). It outputs to Dm8 neurons in medulla layer M6 (Gao et al., 2008; Sancer et al., 2019). It receives synaptic input from photoreceptor cell R8 of the same column (Takemura et al., 2008; Takemura et al., 2015), mostly in M3 (Takemura et al., 2008). Connectivity to Dm8 based on EM data (Gao et al., 2008). Connectivity with R8 based on EM data (Takemura et al., 2008; Takemura et al., 2015). pR7 fly_anatomy.ontology FBbt:02000006 VFB:FBbt_02000006
