One of the fundamental functions of the premotor cortex is that of retrieving appropriate motor acts in response to sensory stimuli. Evidence has been provided that action retrieval can occur in response to two-dimensional patterns, color, and size and shape of three-dimensional objects. The present data indicate that in addition to these physical factors, retrieval can also occur in response to the meaning of the gestures made by other individuals. If one considers the rich social interactions within a monkey group, the understanding by a monkey of actions performed by other monkeys must be a very important factor in determining action selection. Thus, the capacity of inferior premotor neurons to select actions according to gesture meanings fits well in the conceptual framework of current theory on the functions of premotor cortex and expands it to include movement selection related to interpersonal relations.

The right theory of mirror neuron function. Guess who said it.
A quote on mirror neuron function. I think it is spot on, as discussed in The Myth of Mirror Neurons. Who said it? (It wasn't me.)
