Document Summary

Active when performing an action or watching another perform the same action. In monkey studies, mirror neurons fired while grasping or watching another grasp a particular object but not other objects grasping or watching another grasp an object for a specific purpose but not for another purpose. Possible neural basis of social cognition (knowledge of others" mental processes e. g. , intentions) You want to know what the person is going to do through their actions. Located in precentral gyrus of the of the frontal lobe. Diff regions are responsive for diff locations somatotopic organization motor homunculus initial studies by penfield used brief low-intensity stimulation (initially documented somatopic organization) elicited simple motor reflexes however, longer more realistic stimulation elicit more complex and naturalistic movements. The motor mapping - such as controlling specific muscles happens lower down. In the primary motor cortex, focuses on specific movement firing of neurons is often correlated with end goal of movements, even if different trajectory taken.
