Hi all! I was just looking at a diagram of the human facial nerve. The image shows the "root" exiting the left side of the brain and extending to the right side of the face. Likewise a nerve from right to left. This is how the entire nervous system is laid out, as I understand it. Left side of brain goes to right side of body. While I can't think of any reason for this NOT to happen, neither can I think of a good reason it should be the case. Might there be some advantage here? Or is it just one of those anomalous things? Ideas?
