Ramachandran: Mirror Neurons and the Brain in the Vat

Snip from an essay on EDGE.org by neuroscientist V.S. Ramachandran:

Researchers at UCLA found that cells in the human anterior cingulate, which normally fire when you poke the patient with a needle ("pain neurons"), will also fire when the patient watches another patient being poked.

The mirror neurons, it would seem, dissolve the barrier between self and others. [1] I call them "empathy neurons" or "Dalai Llama neurons". (I wonder how the mirror neurons of a masochist or sadist would respond to another person being poked.)

Dissolving the "self vs. other" barrier is the basis of many ethical systems, especially eastern philosophical and mystical traditions. This research implies that mirror neurons can be used to provide rational rather than religious grounds for ethics (although we must be careful not to commit the is/ought fallacy).
