ScerGAL4NP0302 drives expression in around 120 medulla columnar neurons MC61.
Inhibition of synaptic transmission in Scer\GAL4NP0302 neurons leads to aberrant phototaxis behavior (low phototaxis index) towards UV and green (but not blue) light; navigation towards shorter wavelength of light (but not detection of ambient light) is impaired by silencing these neural circuits.
