Abstract
In recent years, functional magnetic resonance imaging has been used to determine the interaction between chewing and brainactivity. However, the factors influencing the activity of the motor cortex have not been fully elucidated. Therefore, the presentstudy investigated the influence of the magnitude of bite force on brain activity. Fifteen right-handed healthy subjects (24-32 years; mean age, 27.8 years) were included. Sustained, constant clenching with small and large forces comprised the motortask. The spatial extent of the functional magnetic resonance imaging signal in the primary sensorimotor cortex increased withan increasing bite force in all subjects. These findings indicated the possibility of measuring the activated area in the primarysensorimotor cortex during clenching using functional magnetic resonance imaging, which revealed that the brain activity wasrelated to the magnitude of the bite force.

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
