Abstract
Paired-pulse transcranial magnetic stimulation (TMS) was used to examine changes in cortical excitability during action observation. We stimulated the left primary motor cortex (M1) of eight healthy volunteers during rest, observation of handwriting and observation of arm movements. Motor evoked potentials (MEP) were recorded from the first dorsal intereosseous (FDI) and biceps (BIC) muscles. Our results showed that action observation induced a facilitation of the MEP amplitude evoked by the single test stimulus and reduced intracortical inhibition and facilitation at 3 ms and 12 ms interstimulus intervals (ISIs), respectively, during paired-pulse stimulation. These changes were specific for the muscle involved in the observed action. Our study presents further evidence that motor excitability is significantly modified when the subject observes an action performed by another individual.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
