Lastly we are interested in cases where our predictions fail and unpublished data linking transmitters, neuropeptides, gap-junctions, post-synaptic receptors, co-transmisison combinations to EM. Please get in touch (Alexander_Bates[at]hms.harvard.edu) with any insights.

But we feel our work is a big step forward. Our data (zenodo.org/records/1059...github.com/funkelab/syn...codex.flywire.aiVirtualFlyBrain.org.
Not quite mission complete. We want more annotations. E.g. receptor localisation delineates excitatory from inhibitory glut connections, moving our +/ - labels to individual connections. Their annotation could enable ML to extract this molecular information from EM at scale.
Which proxy for synaptic signs!... With major assumptions, e.g. no co-transmission, and that glutamate is inhibitory - but, it seems ~80% of brain neurons may express both excitatory and inhibitory GluRs, and co-transmission esp. in monoaminergic neurons is reasonably common.
Yet overall, we had predictions which we felt were pretty good, across several data sets that together make up a whole (amalgam) Drosophila melanogaster nervous system! The neurotransmitter proportions turned out similar to those suggested by single-cell RNA-seq studies.
