Abstract
In animal models, the habenula has been identified as a key structure involved in depression. Thanks to recent technological advancements, a burgeoning body of work has also investigated the habenula in the context of human mood disorders. This scoping review aims to synthesize findings from human studies that pertain to the habenula and its relationship with mood disorders. The review was conducted according to PRISMA guidelines. The literature search was performed with PubMed and yielded 93 articles, of which 50 articles were included in the review. We found that the evidence for baseline habenular hyperactivity in human depression is mixed. As for findings from resting-state functional connectivity (RSFC) studies, they were mainly inconsistent across studies. Moreover, we found no evidence indicating that mood disorders are linked to changes in the volume of the habenula. In order to enhance the replicability of findings, given the small size of the habenula, higher image resolution and larger samples are recommended for future studies.

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
