Mirror Neurons

Finding
Gallese et al. found neurons in macaque premotor cortex that fire for both performed and observed actions. In humans, mirror system activity was identified via fMRI and TMS by Mukamel et al. (2010). These neurons use the same code for self and other action. They are tuned to goal-directed behavior, not meaningless motion. Rizzolatti and Craighero (2004) provide balanced review.
Pattern Mapping
Alignment — Same neural code for self and other action. The system does not maintain separate representations; it aligns the coding of performance and observation. This is structural alignment between first-person and third-person.
Proportion — Mirror neurons are tuned to goal-directed behavior, not meaningless motion. They respond proportionally to the intentional content of what is observed.
Connections
- Hox Genes — both are the same code used across different contexts (species for Hox, self/other for mirror neurons) (→ Meta-Pattern 12 - Conservation and Invariance)
- Gallup Mirror Self-Recognition — MSR requires distinguishing self from other in a mirror; mirror neurons blur self-other boundaries at the neural level
- Girard Mimetic Desire — mirror neurons may be the neural substrate of mimetic desire: we simulate others’ actions, potentially including their desires
- Cooley Looking-Glass Self — Cooley’s theory is social mirroring; mirror neurons are neural mirroring — different levels of the same phenomenon
- Epigenetics — both show that the same underlying structure produces different functional outcomes depending on context
Status
Established in macaques. Human role debated. Rizzolatti & Craighero (2004) is the balanced review. Overclaiming about empathy and language origins is common in popular accounts.
The mapping to the five properties is this project’s structural interpretation.
