It receives most of its inner (R7/R8) photoreceptor input from the R7 photoreceptors of pale ommatidia (Kind et al., 2021). Its axon innervates lobula layer 5 (Kind et al., 2021). It provides input to the lobula intrinsic neuron Li4 via many synapses (Lin et al., 2016). It is a cholinergic neuron (Karuppudurai et al., 2014). The neurotransmitter was assessed by immunohistochemistry (Karuppudurai et al., 2014). Connectivity in the lobula was assessed by GRASP and double-labeling EM (Lin et al., 2016). Photoreceptor input determined from EM (Kind et al., 2021). Tm5b VFB:FBbt_00110073 FBbt:00110073 lobula intrinsic neuron Li4 photoreceptor cell R7 of pale ommatidium
