Head growth and cranial assessment at neurological examination in infancy
Bibliographic record
Abstract
The most dramatic increase in brain volume occurs in the last three months of fetal life and the first two years after birth. Concomitantly, the skull follows the volumetric increase in the cerebral hemispheres mostly by passive adaptation. The relationship between head and brain growth explains why the classical neurological assessment in infancy universally includes measurement of head circumference (HC). However, this crude information derived from HC measurement remains insufficient to qualify brain growth. One way to better document the relation between brain and skull could be to rely on the correlation between HC and body growth parameters, given a general agreement on the definition of proportionate and disproportionate head–body growth. Significant information with respect to the integrity of the underlying cerebral hemispheres can also be provided by systematic palpation of the main cranial sutures. In particular, the distension or overlapping of the squamous sutures which are strategically located at the junction of the cranial vault and the cranial base could be a valid marker of brain growth disorder.

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.
