Maintained directional navigation across environments in the Morris water task is dependent on vestibular cues.
Bibliographic record
Abstract
An experiment was designed to test the hypothesis that an internally generated sense of spatial orientation contributes to navigation by rats in the Morris water task and to determine whether this strategy is dependent on vestibular cues. Rats were trained in a standard hidden platform procedure in which they received 8 daily swim trials. In a probe test, rats were carried in an opaque box to a pool located in a novel adjacent environment. During transport, 1 cohort of rats received a disorientation procedure, composed of gentle rotation in the box, while a second cohort served as transport controls. Upon being placed in the pool in the novel room, controls displayed a preference for the pool quadrant predicted by a retained directional response across rooms, whereas disoriented rats failed to display a preference for the same quadrant. Furthermore, control rats swam faster and more directly toward the target quadrant. Together, these findings suggest that rats retain a directional response based on vestibular cues across environments, which can be used to disambiguate geometrically equivalent locations in a novel room and apparatus.

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.
