Abstract
Previous studies have shown that medial prefrontal cortical regions, such as the anterior cingulate cortex (ACC), play a key role in the expression of remote spatial and contextual memory. To evaluate whether this role is conserved in hippocampal-independent tasks we trained mice in the conditioned taste aversion (CTA) paradigm. Lidocaine-induced inactivation of the ACC blocked the expression of CTA tested one month (remote), but not one day (recent), after conditioning with either a weak or strong unconditioned stimulus (US). These data suggest that the ACC may play a conserved role in remote memory, regardless of memory strength or content.

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
