Abstract
Use: A substantial proportion of patients with depression fail to respond to conventional treatment. Transcranial magnetic stimulation (TMS) is a powerful new technology that holds promise both as an antidepressant treatment and as an inves-tigative tool in understanding the pathophysiology of depres-sion. The magnetic stimulator consists of a power supply, a capacitor and the controlling electronics. The capacitor dis-charges 3000 to 8000 amps through a handheld wire coil, momentarily creating a 2- to 3-Tesla magnetic field around the coil. When the coil is held against the skull, a secondary electrical current is painlessly induced in underlying cortical neurons and action potentials may be triggered. It is also pos-sible to induce changes in the neurons ’ electrochemical ex-citability, which last long after the stimulation has been termi-nated. This process appears to be directional and frequency-

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.
