Abstract

fetched live from OpenAlex

A Hand Path Displacement at the Beginning, Middle and End of Learning and Relearning.Representa2ve hand paths from the beginning, middle and end of gradual adapta2on on day one and abrupt adapta2on on day two for each condi2on.Each hand path is a single trial and hand posi2on is displayed as displacement in cm.Day one: beginning, trial number 70/363; middle, trial number 133/363 and end, trial number 155/363.Day Two: beginning, trial number 228/363; middle, trial number 288/363 and end, trial number 363/363.B Perpendicular Devia1on at Maximum Velocity Across all Trials Channel trials were removed to produce visualiza2on of hand path kinema2cs from baseline (trials 0 to 53) to day one training (trials 59 to 208) to day two relearning (trials 209 to 363).Perpendicular devia2on (PD) measured the amount of devia2on from straight-line hand paths at peak movement velocity.PD at 0 indicates complete compensa2on for the force while nega2ve values indicate less compensa2on, that is, devia2on moving in the same direc2on of the force perturba2on.C Grouped Perpendicular Devia1on at Max Velocity A summary plot of PD during baseline, day one learning, day two reten2on, and day two relearning.Twenty consecu2ve non-channel trials were grouped at each phase to produce a mean perpendicular devia2on for each condi2on. Two Blocks of iTBS on MEPs 69A Experimental Procedure: iTBSx1 to M1.The mean of biceps MEPs were obtained before and a^er two blocks of iTBS.B Mean MEP Amplitudes Before and AMer iTBSx2 to M1. MEP amplitude was quan2fied as the absolute peak-to-peak value of EMG recordings.Individual par2cipant means are ploaed before and a^er iTBSx2 to M1. C EMG Response Before and AMer iTBSx2 to M1. MEPs were observed between 10 and 50ms of s2mula2on onset (0ms).The mean MEP waveform across par2cipants is displayed before s2mula2on (pink) and a^er s2mula2on (green).D Experimental Procedure: iTBSx2 to S1.The mean of biceps MEPs were obtained before and a^er two blocks of iTBS.E Mean MEP Amplitudes Before and AMer iTBSx2 to S1 MEP.amplitude was quan2fied in the same way as B. Individual par2cipant means are ploaed before and a^er iTBSx2 to S1. F EMG Response Before and AMer iTBSx2 to S1.The mean MEP waveform across par2cipants is displayed before s2mula2on (pink) and a^er s2mula2on (red).

Full frame distilled prediction

Teacher imitation

Not 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.
