I always thought the big advantage of human/biological neurons was that they each could have 10.000 axons/dendrites and each one of those could also interact with thousands and thousands of neurons; and new connections could be created on the fly. And I'm sure some neurons could perform complex computations themselves, but artificial neurons can also do that, but so far we haven't found that to be particularly useful and only use a bunch of simple non-linear functions.
