AGE-RELATED CHANGES IN MOTOR ABILITY AND MOTOR LEARNING IN TRIPLE TRANSGENIC (3×TG-AD) AND CONTROL (B6129SF1/J) MICE ON THE ACCELERATING ROTAROD
Bibliographic record
Abstract
Student Award-Winning PaperMouse models of Alzheimer’s disease (AD) show both cognitive and neuromotor impairments. We measured motor ability and motor learning of male and female triple transgenic (3×Tg-AD) and control (B6129SF1/J) mice on the accelerating Rotarod in a cross-sectional design at 2, 6, 9, 12, and 15 months of age. At all ages except for 2 months, transgenic mice performed better and had a steeper motor learning curve than controls. Female mice showed better motor performance than males, while males had a steeper learning curve than females. Age did not have a significant main effect on Rotarod performance. However, age and genotype showed an interaction, where the performance of 3×Tg-AD mice peaked at 6 months of age and decreased as age increased. The performance of controls was below that of 3×Tg-AD mice at each age. Behavioural differences seen in the 3×Tg-AD mice may help us to understand the development of neuromotor dysfunction in AD.Keywords: Alzheimer’s disease, Alzheimer models, Amyloid beta, motor ability, motor learning, Rotarod, tau, transgenic, 3×Tg-AD mice

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.
