General Information
Term photoreceptor cell R7 of pale ommatidium ID (Ontology) FBbt:02000006 (Fly Anatomy)
Definition 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).[ FlyBase:FBrf0180690 FlyBase:FBrf0205531 FlyBase:FBrf0206213 FlyBase:FBrf0230092 FlyBase:FBrf0243430 ]
Also Known As "pR7" ; "R7p"
Comment 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).
