ScerGAL4Gr64c.4.5 drives expression in adult abdominal multidendritic neurons with with dorsal processes extending along the left-right axis, as well as in multidendritic neurons with lateral processes extending anteroposteriorly; these major processes have several protruding dendrites. Additionally, expression is driven in multidendritic neurons with ladder-like processes along the dorsal abdominal wall. ScerGAL4Gr64c.4.5 also drives expression in neurons innervating the male reproductive organs, mostly innervating the accessory gland; and in neurons innervating the female reproductive organs, mostly innervating the common oviduct, lateral oviducts, or ovaries.
