Abstract
Autism is a highly debilitating disorder that has recently displayed a dramatic rise in incidence. In order to realistically study preventative and remedial strategies, it is important that we develop and understand useful animal models of the disorder. The purpose of this study was to investigate the efficacy of the prenatal valproic acid (VPA) rat model of autism by examining the neuro-anatomical and behavioural outcomes of offspring exposed to this paradigm. The VPA-treated rats exhibited behavioural changes in the delayed non-match-to-sample task, novel object recognition, activity box, and Whishaw tray reaching task. Anatomically, there was a reduction in brain weight and cortical thickness, along with decreased dendritic branching in the orbitofrontal cortex (OFC) and medial prefrontal cortex (mPFC), and decreased spine density in the mPFC, OFC, and cerebellum. Behavioural and anatomical findings from this study produced reliable results indicating that prenatal VPA exposure may be a viable model for the study of autism in rats.

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
