Abstract

fetched live from OpenAlex

A 77-year-old man with essential hypertension abruptly developed marked hemiataxia, and paresthesia and decreased vibration sensation in the left-sided upper and lower extremities. There were no other neurological abnormalities. Cranial diffusion-weighted magnetic resonance imaging demonstrated a localized infarction in the right-sided median zone of the middle pons. Cranial magnetic resonance angiography finding was normal. Under anti-platelet agent, he became asymptomatic within 5 days. Impairment of the descending corticopontine fiber and/or pontine nucleus causes contralateral hemiataxia. Involvement of the medial lemniscus induces paresthesia and disturbance of vibration sensation in the contralateral limbs. In our patient, not only the cerebro-ponto-cerebellar pathway but also the medial lemniscus might be damaged. Hemiataxia with ipsilateral sensory disturbance is commonly regarded as indicating sign of lateral thalamic lesion. However, we emphasize that hemiataxia with ipsilateral sensory disturbance rarely results from infarct lesion in the contralateral median zone of the middle pons.

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.
