ScerGAL4GMR37F03 drives expression mainly in adult fruitless aDT-g neuron, but also drives expression in approximately 4 neurons that innervate the lateral horn, approximately 3 neurons in the dorsal ventrolateral protocerebrum, first and third thoracic segments, as well as neurons of the abdominal ganglion.
Inhibition (using shi1.UAS at 30[o]C) of Scer\GAL4GMR37F03 neurons in adult females does not significantly affect receptivity to mating, compared to controls; in males, courtship pulse song-induced locomotion is not significantly affected, compared to controls.
