ID: FBbt_02000005

Photoreceptor cell R7 that is part of a yellow ommatidium and expresses Rhodopsin 4 (Wernet and Desplan, 2004). It outputs to transmedullary neuron Tm5a (Gao et al., 2008; Karuppudurai et al., 2014) and 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 with Tm5a inferred from EM reconstructions from a single medulla column (Gao et al., 2008) and selective arborization in yellow columns (Karuppudurai et al., 2014). 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).
