You can now use NBLAST to find similar neurons, or GAL4 drivers that label a neuron of interest. The implementation is described here, and the how, with video demos here. You can start NBLASTing right away on the online app!
Neurons listed in the NBLAST results are linked to VFB, so you can see them on the viewer, together with any other image.
And see here how to find GAL4 drivers that label specific neurons.
