Pseudo‐affective visceromotor responses and HPA axis activation following colorectal distension in rats with increased cholinergic sensitivity
Bibliographic record
Abstract
We analysed visceromotor (VMR) and corticosterone responses to colorectal stimuli under control conditions and following acoustic stress in rats selectively bred for increased sensitivity to cholinergic agonists, the Flinders Sensitive Line (FSL) rats, compared with Flinders Resistant Line (FRL) rats. FSL rats demonstrated a significant VMR response at the smallest distension pressure, whereas no response was evident in FRL controls. FSL rats also demonstrated enhanced VMR responses at both larger distension levels compared with FRL rats. Colorectal distension (CRD) produced significant increases in serum corticosterone levels, which were comparable in FRL and FSL. Noise stress induced divergent corticosterone responses in FRL and FSL, but did not affect VMR to CRD in either group. These data suggest that FSL rats show altered VMR responses to CRD and disturbed hypothalamic-pituitary-adrenal axis responses to acute stress.

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.
