I found an interesting bit of scientific evidence that may lead to the probability that Mr. Thompson isn't just blowing a lot of smoke. It revolves around
mirror neurons, as presented by Marco Iacoboni, a neuroscientist and director of the Transcranial Magnetic Stimulation Laboratory at the David Geffen School of Medicine at UCLA. Quoting from the book
"What Is Your Dangerous Idea: Today's Leading Thinkers on the Unthinkable" from Iacoboni's essay entitled "The Problem With Super Mirrors":
Marco Iacoboni wrote:
Mirror neurons are cells located in the premotor cortex, the part of the brain relevant to the planning, selection, and execution of actions. In the ventral sector of the premotor cortex, there are cells that fire in relation to specific goal-related motor acts, such as grasping, holding, and bringing to the mouth. Surprisingly, a subset of these cells--what we call mirror neurons--also fire when we observe somebody else performing the same action. The behavior of these cells seems to suggest that the observer is looking at his or her own actions reflected in a mirror while watching somebody else's actions. My group has shown, in several studies, that human mirror neuron areas are also critical to imitation. There is evidence that the activation of this neural system is fairly automatic, thus suggesting that it may bypass conscious mediation. Moreover, mirror neurons also code the intention associated with the observed actions, even though there is not a one-to-one mapping between actions and intentions. (I can grasp a cup because I want to drink or because I want to put it in the dishwasher.) This suggests that the system can indeed code sequences of action (that is, what happens after I grasp the cup), even though only one action in the sequence has been observed.
Some years ago, when we still were a very small group of neuroscientists studying mirror neurons and just starting to investigate the role of mirror neurons in intention understanding, we discussed the possibility of super-mirror neurons. After all, if you have such a powerful neural system in your brain, you also want to have some control or modulatory neural mechanisms. We now have preliminary evidence suggesting that some prefrontal areas have super mirrors.
I think super mirrors come in at least two flavors. One is inhibition of overt mirroring and the other--the one that might explain why we imitate violent behavior, which requires a fairly complex sequence of motor acts--is mirroring of sequences of motor actions. Super-mirror mechanisms may provide a fairly detailed explanation for imitative violence that arises after exposure to media violence.
