Abstract
Genetically encoded fluorescent reporter iGluSnFR for extracellular glutamate (Glu) sensing and genetically encoded calcium indicator GCaMP6f for calcium sensing are applied with two channel fiber optic recording system in combination with BOLD fMRI. The intracellular calcium signal from both neurons and astrocytes, as well as the extracellular glutamate signal, were recorded with concurrent BOLD fMRI signal from both hemispheres of anesthetized rats, showing unique temporal dynamic pattern. This multi-modal fMRI platform allows us to specify the neurovascular signaling through the neuro-glial-vascular network and provide better understanding on the cellular and molecular interaction underlying the BOLD fMRI signal.

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
