In the adult brain, ScerGAL4113 drives expression in 4 specific neurons bundles (FSB) in the lateral protocerebrum, in the optic lobe, cervical connective, giant fiber neuron, ascending tract of the ventral nerve cord (ATVNC) and mesothoracic segment. In the larval brain, expression is detected in the region where the two brain lobes meet (IJ) and in the ventral nerve cord.
