mirror neuron
n.— «The most significant finding was the discovery of “mirror neurons,” a widely dispersed class of brain cells that operate like neural WiFi. Mirror neurons track the emotional flow, movement and even intentions of the person we are with, and replicate this sensed state in our own brain by stirring in our brain the same areas active in the other person.» —“Friends for Life: An Emerging Biology of Emotional Healing” by Daniel Goleman New York Times Oct. 10, 2006.
