axon & photoreceptor cell R8 | somatic clone, with Scer\GAL4Act5C.PI, stanRNAi.intra.UAS
Expression of standsRNA.intra.Scer\UAS and standsRNA.extra.Scer\UAS in lamina target neuron clones, under the control of Scer\GAL4Act5C.PI, results in R8 axon guidance defects. R8 axons display thickened terminals and fasciculate with R7 and R8 axons in adjacent medulla neuropil columns.
