From David Biro at the Literature, Arts and Medicine blog:
One of the most exciting, recent discoveries in science has been the mirror neuron. First isolated in monkeys and later found to exist in human beings, these neurons (and groups of neurons) are active not simply when we are moving and emoting but when we observe others moving and emoting. Our brains, as it were, re-enact or mirror the movements and emotions of other people as we watch them. Although scientists are still working out the implications of this extraordinary finding, it is almost certain that the brain’s mirroring system contributes to the profoundly social nature of human beings and may well be responsible for many of our greatest collective achievements: language, social institutions, and culture (4).
Many scientists also believe that neuronal mirroring can reflect in two directions, illuminating both the external world (of others) and the internal world (of self). By constantly observing and imitating others, we not only learn about them but about ourselves: How we see and think of ourselves; the meanings we ultimately give to our most intimate and “unsharable” experiences like pain; indeed the ongoing project of human creation in general as it works to fill the world with things that possess the capacity to reflect our humanity (5).
Thinkers like Sartre, Foucault and Lacan may have been exquisitely prescient. Mimesis may well turn out to be a prerequisite or stepping stone to self-knowledge. We observe, reproduce, impose patterns, and thereby understand. We can do this with objects that happen to cross our field of vision… But we could also do this on a more sophisticated level. If a potential doppelganger doesn’t exist we can invent one … as many artists do in their poems and paintings. After finishing his masterwork, Flaubert is famously reported to have said of his creation: Emma Bovary, ces’t moi. The re-production leads to recognition. The same thing that painters do perhaps more self-consciously in their self-portraits and in the case of Frida Kahlo, her double self-portraits. Here the dictum of philosopher Nelson Goodman is most transparently realized: Comprehension and creation go on together (6).
