We watched mice follow scent trails drawn on an “endless” treadmill. By manipulating trail geometry/statistics, perturbing mouse nose & brain, and modeling behavior with a Bayesian framework, we show that mice use predictive (rather than reactive) strategies.

White text on white background instructing LLMs to give positive reviews is apparently now common enough to show up in searches for boilerplate text.
