Are these projects about emulation? The Oregon and Rome projects seem to treat the brain as a black box, rather than taking advantage of Brenner's connectome. I'm not sure about the others. That doesn't tell us much about the difficulty of emulation, except that they thought their projects were easier.
Brenner's connectome is not enough information. At the very least, you need to know whether synapses are exciting or inhibiting. This pretty much needs to be measured, which is rather different than what Brenner did. It might not require a lot of measurement: once you've measured a few, maybe you can recognize the others. Or maybe not.
The oregon one looks to me like it was about emulation: each of the 302 neurons will be implemented according to available anatomical and physiological data.
The rome one I think you may be right.
Is the nematode too small to measure whether synapses are exciting on inhibiting?
I was basing my judgement on the Oregon papers. I suppose that there may be emulation attempts lurking behind other non-emulation papers.
It's also possible they only proposed to do emulation, but never got funded.
