Expression of ScerGAL4esg-c287a is seen within two small clusters of neurons lying laterally to the antennal lobe and the AMMC. These cells send projections to arborize in the antennal lobe, and presumptive axons project posteriorly and dorsally along the antenno-cerebral tract to terminate ipsilaterally and contralaterally in dense regions of synaptic arborizations in the medial and lateral protocerebrum.
