Wait, does that mean that we can fully simulate the outside behavior of a worm brain?
No, they just added lots of data for one of the multiple things that current emulation efforts (just like neural networks / brain-inspired AI software) so far didn't even include (neuropeptides).
There's no reason for why it would now be possible to simulate complex nervous system processes, but maybe this could enable getting closer to that. I don't know what you mean with "outside behavior" though. Maybe you're referring to the behavior in some simulation like this?
