Strictly congruent neurons (about 30 percent of the mirror neurons in area F5) discharge when a monkey performs a particular action, such as grasping an object with the thumb and index finger (precision grip), and when the monkey observes the same movement. Types of mirror neuronsĭifferent types of mirror neurons can be distinguished, among them strictly congruent and broadly congruent neurons.
In humans, neurons that discharge during the execution and perception of actions have been identified in various parts of the brain, including in the medial frontal cortex and in the medial temporal cortex. Those two brain areas work in concert and receive input from areas involved in the perceptual processing of biological movement, such as the superior temporal sulcus (STS). In the macaque brain, those areas include area F5 of the inferior frontal cortex (ventral premotor cortex) and the inferior parietal lobule (IPL). Small populations of mirror neurons have been found in areas of the brains of monkeys, humans, and birds. Mirror neurons are of interest in the study of certain social behaviours, such as empathy and imitation, and may provide a mechanistic explanation for social cognition. Thus, the neurons “mirror” others’ actions. Mirror neuron, type of sensory-motor cell located in the brain that is activated when an individual performs an action or observes another individual performing the same action.
