There are several orders of magnitude fewer neurons in the fly vs humans. For the fly, we are reconstructing neural processes using EM slices that range from 50 nm to 7 nm in thickness. At that scale, we can reconstruct neural processes and actually see synapses -- just because neurons are in proximity doesn't mean they are actually connected in the biological sense. Since I'm not as familiar with human neurons, could you tell me at 10 microns, can you resolve the axons, dendrites, and more importantly the synapses? Any references to papers would be great :)
