Intense dopamine innervation of the subventricular zone in Huntington's disease
Bibliographic record
Abstract
Dopamine exerts a robust promoting effect on adult neurogenesis. Here, we report the presence of an intense dopamine (tyrosine hydroxylase immunoreactive) zone along the ventricular border of the caudate nucleus in patients with Huntington's disease, but not in age-matched controls. This thin (150-400 microm) paraventricular zone was composed of numerous small and densely packed dopamine axon varicosities and overlapped the deep layers of the subventricular zone. Immunoreactivity in the paraventricular zone was 50% higher than in adjacent striatal areas. This intense dopamine zone concurs with the striking increase of neurogenesis noted in the subventricular zone of Huntington's disease patients and indicates that dopamine might play a crucial role in intrinsic mechanisms designed to compensate for the massive striatal neuronal losses that occur in Huntington's disease.

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.
