Neuroimaging Evidence of the Anatomo-Functional Organization of the Human Cingulate Motor Areas
Bibliographic record
Abstract
In the monkey, 3 motor areas have been identified in the cortex occupying the banks of the cingulate sulcus (cgs): A rostral cingulate motor area and 2 caudal cingulate motor areas, 1 located in the dorsal bank and the other in the ventral bank of the sulcus. The homologs of these 3 cingulate motor areas in the human brain are poorly understood. The present functional magnetic resonance imaging study examined the anatomo-functional organization of the cingulate motor areas in the human brain. A subject by subject analysis revealed the existence of 3 motor areas along the cgs and these areas appear to be somatotopically organized. Importantly, these 3 motor areas relate to the specific morphological features of the cingulate/paracingulate cortex. These results demonstrate the location and organization of the 3 cingulate motor areas in the human brain and suggest a well-preserved organization of these motor areas from the monkey to the human brain.

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.
