Figure 1—figure supplement 3. lhx2a-expressing olfactory cells innervate lratd2a dHb neurons.
Axons of lhx2a olfactory mitral cells terminate at mApple labeled lratd2a dHb neurons. Dorsal confocal views of (A) Tg(lratd2a:QF2), Tg(QUAS:mApple-CAAX); Tg(lhx2a:syp-GFP) pre-synaptic labeling (open arrowhead) in a 5 dpf larva. The synaptophysin GFP-labeled pre-synaptic boutons are distributed over approximately 5% of the region occupied by lratd2a neurons. (B) Tg(lratd2a:QF2), Tg(QUAS:mApple-CAAX); Tg(lhx2a:gap-YFP) axon terminal labeling (open arrowhead) in a transverse section of the adult brain at three mpf. Scale bar, 50 μm.
