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 EaglemanIn our current understanding of science, we can't find the physical gap in which to slip free will - the uncaused causer - because there seems to be no part of the machinery that does not follow in a causal relationship from the other parts.
David EaglemanAll activity in the brain is driven by other activity in the brain, in a vastly complex, interconnected network.
David EaglemanIn the traditionally taught view of perception, data from the sensorium pours into the brain, works its way up the sensory hierarchy, and makes itself seen, heard, smelled, tasted, felt - "perceived." But a closer examination of the data suggests this is incorrect. The brain is properly thought of as a mostly closed system that runs on its own internally generated activity.
