Neuron somal size is decreased in the lateral amygdalar nucleus of subjects with bipolar disorder
Bibliographic record
Abstract
OBJECTIVE: Morphometric studies of postmortem brains from subjects with mood disorders have reported altered density of glial cells in the amygdala; however, the nuclear regions have not been examined individually. METHODS: We assessed the size and density of both neuronal and glial cells in discrete amygdalar nuclei in postmortem sections from subjects with major depressive disorder, bipolar disorder (BD) and schizophrenia and from nonpsychiatric control subjects. Three adjacent Nissl-stained sections were examined from each individual. RESULTS: We report significantly decreased neuron somal size in the lateral amygdalar nucleus (LAN) and the accessory basal parvocellular nucleus (ABPC) in subjects with BD, relative to control subjects. These changes in cellular morphology were most prominent in the LAN in sections obtained from the left hemisphere. CONCLUSIONS: These findings add to increasing evidence for neuropathological changes in the amygdala of subjects with BD and specifically implicate the LAN and ABPC in this disorder.

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.
