A typical neuron makes about ten thousand connections to neighboring neurons. Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.
David EaglemanIt is more parsimonious to assume that the sun goes around the Earth, that atoms at the smallest scale operate in accordance with the same rules that objects at larger scales follow, and that we perceive what is really out there. All of these positions were long defended by argument from parsimony, and they were all wrong.

But what has become clearโand really just in the last few centuriesโis that when you look at the electro-magnetic spectrum we are seeing less than 1/10 Billionth of the information that's riding on there. So we call that visible light. But everything else passing through our bodies is completely invisible to us. Even though we accept the reality that's presented to us, we're really only seeing a little window of what's happening.
