Region-specific changes of calcium/calmodulin-dependent protein kinase IV in the mouse brain following chronic morphine treatment
Bibliographic record
Abstract
In this study, we examined changes in expression of calcium/calmodulin-dependent protein kinase IV (CaMKIV) in the mouse brain following chronic morphine treatment. Double immunohistochemical staining showed strong colocalization of CaMKIV with mu-opioid receptors. Chronic treatment with morphine produced an increase in expression of CaMKIV and phosphorylated cAMP response element-binding protein (pCREB) in the CA3 region of the hippocampus, whereas a decrease in CaMKIV and pCREB expression was observed in the caudate putamen. Interestingly, chronic morphine induced a decrease in protein expression of CaMKIV in the basolateral amygdale and the primary somatosensory cortex without any concomitant changes in pCREB. These findings suggest that CaMKIV-dependent signaling may play a role in chronic morphine-induced neuroplasticity in a brain region-specific manner.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
