Drives expression in alpha' and beta' lobes of the mushroom body, and in alpha'/beta' mushroom body neurons.
Scer\GAL4c305a labels a large cluster of excitatory local interneurons with cell bodies located lateral to the antennal lobe. Their axons fasciculate and enter the antennal lobe.
Expression of Scer\GAL4c305a was observed in the alpha' and beta' lobes of the mushroom body at 4 days after larval hatching (late wandering third instar), but not earlier at 2 days after hatching (early third instar).
Scer\GAL4c305a labels the mushroom body alpha'/beta' neurons. Co-expression with a postsynaptic marker labels Kenyon cell terminals in the mushroom body alpha' and beta' lobes. No presynaptic terminals in the calyx are observed.
This line labels larval-born alpha' and beta' Kenyon cells in the third instar as well as elements in the thoracic and abdominal ganglia, mostly sensory terminals from the periphery.
Expression is observed in about half of the the alpha', and beta' neurons of the adult mushroom body, in ellipsoid body neurons and in the antennal lobe.
