Abstract
Little is known about the spatial vision of mice or of the role the visual cortex plays in mouse visual perception. In order to provide baseline information upon which to evaluate the spatial vision of experimentally and genetically altered mice, we used the visual water task to assess the contrast sensitivity and grating acuity of normal C57BL/6 mice. We then ablated striate cortex (V1) bilaterally and re-measured the same visual functions. Intact mice displayed an inverse "U"-shaped contrast sensitivity curve with a maximum sensitivity near 0.2 cycles/degree (c/d). Grating acuity, measured either by discriminating a sine-wave grating from an equiluminant gray, or vertical from horizontal sine wave gratings, was near 0.55 c/d. Grating acuity and contrast sensitivity were reduced significantly following aspiration of V1. The mouse visual system exhibits fundamental mammalian characteristics, including the feature that striate cortex is involved in processing visual information with the highest sensitivity and spatial frequency.

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.
