A Study of the Impact Response of Discrete Regions of the Human Cadaver Brain
Bibliographic record
Abstract
The risk of trauma to the brain due to head impacts is high, despite widespread use of protective equipment and injury mitigation efforts. Mitigation techniques are developed through simulations that utilize complex finite element models of the brain and head. Validation of such models is limited, as existing empirical data is sparse. Due to technical constraints, empirical studies have only revealed broad brain tissue deformation. The objective of this study was to develop a comprehensive methodology for measuring the displacement of discrete brain structures during impact. An advanced X-ray system was used to capture brain motion for two cadaveric specimens at 7,500 fps. Displacement of brain structures was determined for 7 impacts on each specimen. Motion trends were region dependent, with some regions exhibiting multi-modal displacement. Displacement of discrete structures including the corpus callosum was measured. These methods will help clarify the response of the brain to impact.

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.
