Abstract
Studies of mood provocation in remitted patients with depression have enabled the description of specific brain changes relevant to depression relapse vulnerability. Because patients in these studies were also receiving maintenance pharmacotherapy, the ability to subtract out the drug effect from the changes observed is reduced. Our study addresses this concern. Changes in regional cerebral blood flow (rCBF) among 11 medication-free, remitted patients with unipolar depression relative to baseline state were assessed with [(15)O]H(2)O positron emission tomography (PET) following provocation of sadness. Participants showed decreased activation in prefrontal cortex similar to those reported for remitted, medicated patients undergoing mood challenge, as well as for acutely depressed patients who were medication free. Previously reported mediofrontal changes in remitted patients are unlikely to be a consequence of maintenance medication and more likely are evidence of relapse vulnerability.

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
