A neuron that fires both when an organism performs an action and when it observes the same action performed by another, thought to underlie imitation and empathy.
From 'mirror' (reflecting) + Greek 'neuron' (nerve). Discovered by Giacomo Rizzolatti's team in macaque monkeys in the 1990s.
Mirror neurons fire when you DO something AND when you WATCH someone else do it — they might be the brain basis for empathy, imitation, and understanding others.
