Differential startle reactivity following central CCK-8S and systemic boc CCK-4 administration in mice: Antecedent stressor history and testing condition.
Bibliographic record
Abstract
The influence of intraventricular cholecystokinin-8S (CCK-8S) and systemic N-t-Boc-Trp-Met-Asp-Phe-amide (Boc CCK-4) was evaluated in the acoustic and fear-potentiated startle paradigms in CD-1 mice. In the light + tone startle condition. CCK-8S increased startle 168 hr after administration, compared with saline. In the tone startle condition, CCK-8S decreased startle immediately and 24 hr after administration, compared with saline. Among nonshocked mice, CCK-8S increased startle at 48 and 168 hr, compared with saline. In the light + tone condition, 5 microg Boc-CCK-4 did not influence startle, whereas 15 microg Boc CCK-4 decreased startle immediately, 24 hr, and 48 hr following administration. Results demonstrate that antecedent environmental experiences interact with subsequent pharmacological challenges in provoking the temporal expression of alterations in startle magnitude.

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.
