Abstract
Abstract The objective of the present article is to provide an introduction to the most widely used method of imaging the functional neuroanatomy of the human brain. The inferential relationship between neural activation and a magnetic resonance signal change is described in detail. The contrast between an active state and a baseline depends on an increased ratio of oxyhemoglobin to deoxyhemoglobin, a longer transverse relaxation time ( T ), decreased levels of paramagnetically induced dephasing, and a consequently stronger signal in the active state. Issues pertaining to image interpretation, spatial and temporal resolution, and image stability are described. © 2003 Wiley Periodicals, Inc. Concepts Magn Reson 16A: 5–15, 2003

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
