In the adult brain, ScerGAL4C774 drives expression in 4 specific neurons bundles (FSB) in the lateral protocerebrum, in the mushroom body, giant fiber neuron, axons of the vertical cells of the lobula plate (AVCLP), central complex and in the axons linking the lateral protocerebra. In the larval brain, expression is detected in the region where the two brain lobes meet (IJ).
