At this point, it's fairly clear that there is no mind body distinction. The "mind" is an emergent property of 10^11 neurons performing complex processing operations on streams of sensory data. If you take away pieces of this machine, corresponding parts of the "mind" also disappear. I'm not sure why this keeps people up at night.

What really interests me (as a PhD student in Neuroscience at Stanford), is how it works, and how the uncoordinated action of neural networks leads to complex behaviors.
