A dopamine D3 receptor partial agonist blocks the expression of conditioned activity
Bibliographic record
Abstract
The partial dopamine D3 receptor agonist BP 897 attenuates cocaine seeking suggesting that BP 897 will attenuate conditioned activity to environmental stimuli paired with amphetamine. During conditioning, amphetamine (2.0 mg/kg) stimulated activity and co-treatment with BP 897 (1.0 mg/kg) had no effect. In the saline test, groups conditioned with amphetamine or amphetamine plus BP 897 showed conditioned activity. Treatment with BP 897 in the test following conditioning with saline produced no significant effect but following conditioning with amphetamine BP 897 blocked conditioned activity. Results extend previous findings that BP 897 attenuates responding for cocaine-paired stimuli to amphetamine-paired stimuli in a different paradigm and support the potential of BP 897 as a therapeutic agent for the prevention of drug seeking.

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.
