c305a	α′/β′	jing	2R (42C1–42B2)	C2H2 zinc finger	axon guidance; embryonic brain development	embryo: midline glia & neurons
c708a	pioneer α/β	CG42684	X (16C5–16C8)	Ras GTPase activation	N/A	embryonic stage 4–6

Inverse PCR uncovered six novel genes expressed in specific subsets of adult mushroom body neurons, suggesting that these genes play roles in the neurons' development and/or function. CNS: central nervous system. Exp.: expression pattern. MB: mushroom body.
