An Update on the Pathophysiology of Major Depression: Neurophysiology for Clinicians
Bibliographic record
Abstract
Work from the last decade has resulted in exciting findings regarding brain changes associated with depression as cutting edge neuroscience has been brought to bear on the pathophysiology of major depression and other psychiatric illnesses. Here we review a current model that links stress, depression and antidepressant effect to cellular and molecular changes in the hippocampus, one of several brain regions implicated in the pathophysiology of depression. There are emerging classes of medication that do not appear to directly modulate monoamines (serotonin, norepinephrine or dopamine) but have antidepressant effects. It is currently unknown whether these medications will have neurobiological effects similar to those discussed below. Therefore instead of referring to antidepressant medication generally, the discussion refers to monoamine modulating antidepressant medications (MMAMs) which primarily include the serotonin reuptake inhibitors, noradrenaline reuptake inhibitors and monoamine oxidase inhibitors.

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.
