The Neurophysiology of Early Motor Resonance
Bibliographic record
Abstract
The discovery of mirror neurons in the monkey brain and the subsequent description of a mirror neuron system (MNS) in humans have triggered unprecedented interest in the neural basis of social cognition. Although the mechanism matching action observation and execution is now well documented in human adults, much remains to be learned about its normal development. In light of accumulating evidence suggesting a link between impaired motor resonance and developmental disorders such as autism spectrum disorder, it is of paramount importance to better understand how the MNS develops and under what specific conditions it appears. Until recently, speculation about the existence of a functioning MNS in the infant brain relied primarily on evidence of imitative behavior shortly after birth. Here, we describe studies that have tackled the issue of detailing MNS properties in the immature brain. Through a variety of neuroimaging techniques, a preliminary description of neurophysiological mechanisms underlying early imitation and action understanding is starting to emerge. We will see, however, that although important first steps have been taken, much remains to be learned about early mirroring processes and their relationship to social behavior.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
