To
claim the mind is in the head is nothing more than cultural conditioning. Please check out the claims of the Ancient Greeks who claimed we thought from the heart.
It turns out the Greeks were wrong, thoughts are based in the head. The connections of all the neurons in our head(which is called the brain) is analogous to the circuitry in a computer, albeit far more complex on a number of different levels. The point to distill is that such massive networks of simplistically functioning constituents can and do produce complex information. Short term memory, for example(which homogenizes with conceptual thinking as fodder for recombination), is achieved by the release of neurotransmitters into the synapse. The memory fades shortly thereafter due to a process called endocytosis, which is when the neurotransmitters are reabsorbed. As your train of thought passes from concept to concept, the corresponding release and absorption of neurotransmitters is happening within your skull. Your thoughts are a result of the stuff inside your head.
That is evidence based reasoning, Mr. Erickson, not cultural conditioning.
