Encyclopedia > Mirror neurons

Mirror neurons are active when a primate performs an action, but also when it observes that action. So far these neurons had been seen in Broca’s and premotor cortical areas of the brain.


See for example this (slightly hyperbolic) essay by Ramachandran on their potential importance in imitation and language http://www.edge.org/3rd_culture/ramachandran/ramachandran_p1.html

Autism linked to mirror neuron dysfunction (859 words)
Mirror neurons are brain cells in the premotor cortex.
The human mirror neuron system is now thought to be involved not only in the execution and observation of movement, but also in higher cognitive processes – language, for instance, or being able to imitate and learn from others' actions, or decode their intentions and empathize with their pain.
Since autistics' mirror neurons respond to their own motion, the researchers say, perhaps their brains can be induced to perceive their own reflected movements as the movements of another human being.
MirrorNeur (2851 words)
By recording the activity of single neurons in the monkey’s premotor cortex, he found that particular neurons became active when a particular action was performed by the monkey, or when the same action was observed being performed by another monkey.
The neuron in the brain is conceptually no different than a neuron in the fingertip that touches the raisins or a cone cell in the fovea that reacts to a photon reflected from a raisin.
Mirror neurons provide strong evidence against this perspective: actually they corroborate the notion that acting and perceiving are two sides of the same coin.
