Professor:...Now, as I am thinking about what I am going to be saying, my muscles in my throat are responding. So thinking can be mesured as muscle activity. Now, the motor theory... yes?

Muscle changes in the hand, just like the muscular changes going on in the throat region for speaking individuals.
