Sensory Temporal Thresholds and Interhemispheric Transfer Times in Multiple Sclerosis: A Preliminary Study of a New Outcome Measure
Bibliographic record
Abstract
This preliminary study investigated the potential of a cerebral lateralization technique that measures both, temporal judgements to sensory stimuli and interhemispheric transfer time (IHTT), as an outcome measure in multiple sclerosis (MS). Tactile stimulation was delivered to one or both hands by mechanical tactile stimulators. Pairs of light emitting diodes were presented to hemifields for visual stimulation. Response consisted of a binary forced-choice (YES/NO) judgement as to the simultaneity of the onset of pairs of stimuli. Both tactile and visual temporal thresholds were significantly higher in MS patients than controls in every presentation condition. IHTT estimates (threshold differences between unilateral and bilateral presentations) for the tactile and visual tasks were also significantly longer in patients than controls. Age correlated with sensory temporal thresholds for the control group only. These findings suggest that this technique may be a useful outcome measure in MS. We hypothesize that myelin injury slows central conduction therefore impairing the ability to judge the onset of sensory stimuli and increasing IHTTs.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
