Augmentation of the Development of Behavioral Tolerance to Cannabinoid Administration through Pavlovian Conditioning
Bibliographic record
Abstract
This investigation examined the effects, in female rats, of a Pavlovian conditioning paradigm on the development of tolerance to hypolocomotion induced by the cannabinoid agonist HU-210. Rats were administered HU-210 and placebo in either an associative or a nonassociative fashion. The results indicated that rats in the associative paradigm developed tolerance significantly faster than those in the nonassociative group (p < 0.03). Subsequently, once tolerance had developed, the associative group of rats was administered HU-210 and placebo in the opposite environments. There were no differences found in locomotion between the CS+ and CS- environments following administration of HU-210. However, when the placebo was administered in the CS+ environment, there was a trend towards increased activity levels (p = 0.06), suggesting withdrawal-like behavior. These findings indicate that the underlying physiological mechanisms of tolerance development in the cannabinoid system are hastened by conditioning, but that these physiological alterations are not contingent upon the associative parameters used for drug administration.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
