I don't understand your reference to Pavlov's dog, it's more comparable to Penfield's work with stimulation of specific points of the brain. Also the ExtremeTech headline is a bit misleading. The related MIT article is a little more clear that this involves memories in a small cluster of neurons, not one memory per neuron as is implied by the heading above. http://www.mit.edu/newsoffice/2012/conjuring-memories-artifi...
