Hotheaded? Keep a cool head. How the water flows in the brain - especially the white matter (the deep parts that we were taught was pretty useless) - may hold one of the keys to autism, short-term memory and other things. Below is an actual map showing the paths of water flow in a section of the brain. Water is a heat-sink. Neurons transmit via action potentials - electrons - electricity.... if your motor gets overheads, it'll blow - ''don't blow your cool''... P.S - being in a state of ''Flow'' has new meaning. All these metaphors exist for a reason, you know. We know more about ourselves collectively as a species than we realize. It's hidden in the language. Analogies analogize _something_. I have no conclusions yet. Just (hopefully) little inspirations.
