The role of the medial prefrontal cortex in regulating interanimal coordination of movements.
Bibliographic record
Abstract
Rats with juvenile play experience display a greater ability in coordinating their movements with social partners than those deprived of such experience, and this may be due to the play-induced neural restructuring of the medial prefrontal cortex (mPFC). The present study investigates the role of the mPFC in interanimal coordination. Rats with and without bilateral mPFC lesions were tested on a robbing-and-dodging task. This food protection task measures the ability of rats to protect pieces of food by gaining and maintaining an interanimal distance between themselves and the rat attempting to rob the food. Given that mPFC lesions have been associated with sensory and motor deficits, the same rats were also subjected to a task to measure skilled motor movements. Rats with bilateral mPFC lesions had more food stolen and displayed an inability to maintain interanimal distance with partner, but did not exhibit any motor or sensory deficits. These findings suggest that the mPFC is involved in interanimal coordination and that the play-induced neural restructuring of this area may account for the enhanced coordination seen in rats with prior play experience.

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.
