Abstract
Recent studies indicate that presynaptic long-term potentiation in the anterior cingulate cortex may contribute to chronic pain-related anxiety. In addition to the anterior cingulate cortex, the insular cortex has also been indicated in chronic pain and its related emotional disorders. In the present study, we used a 64-channel multielectrode dish (MED64) system to record pre-long-term potentiation in the insular cortex. We showed that low-frequency stimulation paired with a GluK1-containing kainate receptor agonist induced N-methyl-D-aspartic acid receptor-independent pre-long-term potentiation in the insular cortex of wild-type mice. This form of pre-long-term potentiation was blocked in the insular cortex of adenylyl cyclase subtype 1 (AC1) knockout mice. Furthermore, a selective AC1 inhibitor NB001 blocked pre-long-term potentiation in the insular cortex with a dose-dependent manner. Taken together, our results suggest that AC1 contributes to pre-long-term potentiation in the insular cortex of adult mice and NB001 may produce anxiolytic effects by inhibiting pre-long-term potentiation in the anterior cingulate cortex and insular cortex.

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
