comment What can we learn from the neural networks of C.elegans to understand human brains?
@Skyler like I said, depends how you mean. Since it's so simple we've learned a great deal how to study neural networks in general from C. elegans, it's basically to NN research what the fruit fly is to genetics and the rat to psychology. In terms of research specifically applicable to humans I don't think there's all that much; C. elegans is a great way to learn about neural networks as a thing, but there's not much that can be extrapolated directly to humans that's not just as applicable to other species.

comment Why does neuroplasticity decrease in adults?
I suspect a great deal of the practical "why" is that further development is much less needed as an adult. Increased neuroplasticity helps in the rare event of brain trauma but it's probably not worth the added cost of neuroplasticity. Remember there;s more to neuroplasticity than learning language.

@Jeff I think perhaps now this is the more useful question: cogsci.stackexchange.com/questions/252/…

comment What is the most complex artificial neural network created to date?
@Jeff practical ANNs like Blue Brain always go for biological realism, obviously an ANN that isn't representative of an NN isn't acceptable but that's not a good usable metric. The metrics I always hear to compare ANNs is always either neuron/synapse count or complexity compared to an animal (simple = C. elegans, complex = cat, Holy Grail = Human). If there's a better measure I'm not aware of it but would love to know of it

@Jeff for the purposes of this question number of synapses should be sufficient as that (and count of neurons, which correlates with it) is how artificial ones are generally gauged. I've edited the question. Some better reading on neural net complexity is here: math.bu.edu/people/mkon/pppp11.pdf

@ArtemKaznatcheev what does neurobiology have to do directly with either in this context? They're both different concepts but neural-network is usually used to refer to artificial ones these days so just that one of the two does make sense.

Fidgeting has been found to be a focus aid, I'll try and find some articles
