This is fascinating considering that the cerebellum contains more neurons than the rest of the brain(!) (source: http://neuroscience.uth.tmc.edu/s3/chapter05.html http://neuroscience.uth.tmc.edu/s3/chapter05.html). I wonder what other problems she experiences (the article only says she started speaking and walking at age 6-7).
- thanatropism 12y agoThe 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.
- pionar 12y agoInteresting. 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).
- thanatropism 12y agoIt's a different kind of neuron altogether. https://en.wikipedia.org/wiki/Purkinje_cell https://en.wikipedia.org/wiki/Purkinje_cell https://en.wikipedia.org/wiki/Cerebellum_granule_cell https://en.wikipedia.org/wiki/Cerebellum_granule_cell
