The cerebellum is a much more primitive neural network, though. It's feed-forward only - it actually looks like a tree in MRIs - so it's a lot harder to encode anything. Normal neural networks ("connectomes") in the brain are massively interconnected in all directions, which allows for parallel computation; with the tree-like, feed-forward-only architecture of the cerebellum, neurons from different "branches" don't communicate.

Interesting. How was it determined that they're feed-forward-only? Can signals not travel back down the "tree"? (Note, I'm not even an amateur neurologist).

It's a different kind of neuron altogether.
