Vasomotor Innervation Fields Of Peripheral Nerves Supplying The Hand: Differences Between Neurovascular And Somatosensory Patterns
Bibliographic record
Abstract
This study's purpose was to thermographically investigate the innervation fields of peripheral nerves to arteries of the hand and compare these neurovascular patterns to established somatosensory patterns. Seventeen normal adult volunteers received peripheral nerve blocks to the radial, median, and ulnar nerves. Palmar and dorsal thermographic images of the hand were taken to identify regions of hyperemia, revealing the vasomotor innervation field for each peripheral nerve. Peripheral nerve vascular innervation patterns displayed marked similarity to somatosensory patterns, with the notable exception that the radial nerve does not appear to innervate vessels of the hand. The vascular innervation field of the ulnar nerve in the hand appears identical to its somatosensory field, whereas, innervation to the remainder of the hand's vasculature seems solely supplied by the median nerve. These findings may help identify neurovascular etiologies of some nontraditional symptom patterns, which may have been previously diagnosed as having no organic cause.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
