Excellent topic. During every action potential every neuron *solves* an n-body problem analog ‘doing’/ execution and the information is electrically carried and integrated in the brain http://neuroelectrodynamics.blogspot.com/p/spike-directivity.html *The fundamental process of computation by physical interaction in the brain has been widely misunderstood*.
