drives expression in a total number of around 6 ring neurons R1 after eclosion and in about 8 neurons per hemisphere after 7 days. Labeled neurons co-express Scer\GAL80ple.PK
Expression of Scer\GAL4c105
is seen in approximately 7 cells in each brain hemisphere that project to the bulb (or 'lateral triangle') of the central complex before bifurcating to project to the posterior ring of the ellipsoid body and to descend through the central brain.
Adult expression is observed in six-ten R1 ring neurons, with cell bodies lateral to the central complex, that arborize in the inner domain of the ellipsoid body and project to the lateral triangle.
