Mirror Neuron System
Canonical definition
The mirror neuron system is a network of neurons in premotor, parietal, and prefrontal cortex that activate both when an Individual performs a goal-directed action and when they observe another Individual performing that action, thereby enabling preconscious representation of others' intentions, automatic imitation of observed behaviours, and rapid social learning without conscious deliberation. [Axiom 7: Preconscious Transmission]
Explanation
Mirror neurons are the biological substrate of Mimesis. They fire predictively, up to 480 milliseconds before an observed action occurs, indicating they represent the goal or intention behind the action, not merely the visible movement. This predictive activation allows the brain to "simulate" others' goals internally, which becomes the pathway through which Mimetic Desire is transmitted: seeing someone pursue an Object activates the same neural circuits that would fire if you were pursuing it yourself, creating an automatic bias toward copying their goal. The mirror neuron system is why humans are such powerful social learners, it's how children acquire language, how cultures transmit skills, and how communities coordinate, but it also makes humans vulnerable to mimetic contagion when combined with Source Opacity.
