Transection of dysmyelinated optic nerve axons in adult rats lacking myelin basic protein
Bibliographic record
Abstract
Injury to myelin or oligodendrocytes may manifest as dysmyelinating or demyelinating conditions of the CNS. Previous studies using dysmyelinated animal models (myelin basic protein mutants) suggest possible axonal dysfunction with complete loss of myelin. In this present study, we evaluated retinal ganglion cell survival after axotomy in MBP mutants to determine if prolonged dysmyelination of CNS axons exerted a detrimental effect on neuronal survival. We demonstrated that the survival of retinal ganglion cells with dysmyelinated axons is identical to retinal ganglion cells with myelinated axons after survival times up to 180 days. In myelin diseases where axon transection is a consistent consequence of demyelination resulting in progressive neurological deterioration, the absence of myelin does not accelerate neuronal death.

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.
