Abstract
C57BL/6 mice were given 0.2% cuprizone (CPZ) for 2 to 6 weeks while controls ate the same diet without CPZ. At various time points the animals were subjected to behavioral tests and their brains were analyzed. Mice exposed to CPZ for 2 and 3 weeks displayed more climbing behavior and lower prepulse inhibition, suggesting an increase in central nervous system activity and impaired sensorimotor gating. In addition, they showed lower activities of monoamine oxidase and dopamine beta hydroxylase in the hippocampus and prefrontal cortex, and had higher dopamine but lower norepinephrine levels in the prefrontal cortex. Mice exposed to CPZ for 4 to 6 weeks had less social interaction, which is an animal correlate of social withdrawal of patients with schizophrenia. Also, these CPZ-exposed mice showed evident brain demyelination, myelin break down, and loss of oligodendrocytes. At all time points the CPZ-exposed mice spent more time in the open arms of an elevated plus maze and exhibited spatial working memory impairment. These data are in line with evidence from human studies suggesting a putative role of white matter abnormality in the pathophysiology of schizophrenia.

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
