ScerGAL4GMR9B08 is a pan-lamina monopolar neuron driver.
ScerGAL4GMR9B08 drives expression in lamina monopolar neurons L1-L5, and their precursors.
ScerGAL4GMR9B08 drives expression in lamina neurons from the third instar larval stage until adulthood; it also drives expression in some medulla neurons and in a subset of photoreceptors early in pupal development.
