It seems the more we learn the less we know about the brain. Why is it that brain activity is so often portrayed as an electrical current when it is in fact a chemical one? It is interesting to note the inherent misconceptions about the brain that we must address. No electricity in the brain, ok, that makes sense based on what we have described as an action potential, so how else has so called 'common knowledge' tricked us? Are there spaces between the neurons, what lies between them?

How does the movement of chemicals create our thoughts? It's strange to think that the mere shifting of voltage in small areas can create such amazing things as our thoughts. I know there is more to it than that but how, how can these thoughts be just the movement of chemicals along a path. How can the act of writing this post be an action potential along an axon? Is this complex process just chemicals?
