Abstract
The structural homeostasis is challenging for neurons, whose axons extend up to meters in large animals, and the axoplasmic mass reaches over a thousand times that of the cell body. Thus, the protein demand may overcome the capacity of the cell body to supply the right protein species, to the right place, in the right time. In this context, a body of evidence indicates that glial cells support the axonal maintenance and regenerative responses by diverse mechanisms of intercellular communication. We showed recently that Schwann cells (SC) transfer ribosomes to axons and also enhance regeneration by means of extracellular vesicles known as exosomes that contain mRNAs, miRNAs and proteins. These findings strongly suggest that the nucleus of the SC supports the machinery for protein synthesis of the axon and participates in the specification of the phenotype of the underlying axon. That the genetic programs of many nuclei modulate the axoplasm on a local basis is akin to a syncytium but at variance with it, the nuclei belong to satellite cells. We propose that the SC-axon unit is a functional syncytium.

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
