I'm not an expert so I could be wrong but over the last 10 years I've seen many papers on various details and behaviors of the C. Elegans nervous system. I agree we have a lot still to learn from it but we certainly seem to know enough to simulate it accurately and get the same kinds of behaviors that we see in the living worm. We've even been able to simulate much larger and more complex systems like the fruitfly eye and direction-tracking system. I really believe that all we need to have is the connectome and the rules it uses to organize and change itself. We don't need to know EVERYTHING about it.
- dardila2 15y agoThe sense I get of it is that they can custom build neural network models of various sub-circuits to produce certain behaviors, but no one has been able to take the connectome and build a 302 neuron model that replicates any behavior. Would you agree? I've searched for quite a long time for something like this and talked to a couple faculty members to no avail, so if you could turn up anything I would be very happy to read about it. I agree with you on your last point: we can replicate behavior without going to a very low level of simulation. However, the case of C. elegans seems like very strong evidence that the connectome and current knowledge of update rules is not enough to create a model of an organism that replicates behavior.
- Devilboy 15y agoI think you are correct, I can't seem to find anyone that's actually simulated the complete nervous system and reproduce any behaviors.
