Tau modulates visual plasticity in adult and old mice
Bibliographic record
Abstract
Tau is a microtubule-associated protein involved in Alzheimer's disease. However, little is known on its physiological function in the healthy central nervous system. Here, we observed that the expression of Tau isoforms was modulated by neuronal maturation and visual experience in the mouse retina and in the visual cortex. The visual function of wild-type (WT) and Tau knockout (KO) mice was evaluated using the optokinetic reflex (OKR), an innate visuomotor behavior, and by electroretinography. Visual tests did not reveal functional impairments in young adult and old Tau KO animals. Moreover, monocular deprivation (MD) was used to increase OKR sensitivity, a plasticity phenomenon depending on the visual cortex. MD-induced OKR sensitivity enhancement was significantly stronger in Tau KO than in WT mice suggesting that Tau restricts visual plasticity. In addition, human Tau expression did not affect visual function and plasticity in a mouse tauopathy model, relative to WT controls. Our results unveil a novel function for Tau in the adaptive mechanisms of plasticity operating in the adult brain subjected to sensory experience changes.

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.
