There is a class of neurons that fire when an individual performs simple goal-directed motor action, such as grasping a glass of water The surprising part was that these same neurons also fire when the individual sees someone else perform the same act. S C I E N T I F I C A M E R I C A N, NOV 2006

irror Neurons Mirror Neurons Neurons in the primate premotor cortex that are activated by performing an action or by watching another monkey or person performing an action. Also seems to exist in humans, in Broca’s area and the primary motor cortex. Humans learn many actions through the observation and itation of the actions of others imitation of the actions of others and the mirror neuron system provides a possible mechanism through which observation can be g translated into action.

Unformatted text preview: iscerning Intention Discerning Intention Inferior parietal lobe recordings from one neuron show intense firing when the monkey grasped a fruit to bring it to its mouth . The neuron’s response was weaker when the monkey grasped the food to place it in a container. This evidence illustrates that the motor system is organized in neuronal chains, each of which encodes the specific intention of e act the act. • Subsets of neurons respond when an individual 1 p performs certain actions and also when the subject observes others performing the same movements. • hese “mirror neurons” provide a direct internal 2 These mirror neurons provide a direct internal experience, and therefore understanding, of another person’s act, intention or emotion. • Mirror neurons may also underlie the ability to imitate 3 another’s action, and thereby learn, making the mirror mechanism a bridge between individual brains for communication and connection on multiple levels....
