Mice had far fewer direct exposures to the non-task-related presented odorants than odorant exposure during the active-training task. (A) Pseudocolor plots of mean trials per minute (active-training) (left panel) and investigations per minute (non-task-related home-cage exposure) (right panels) across 10 days of training (session number). In both paradigms, odorant exposures occurred primarily within the first 5 min of a session. (B) Mean number of trials per minute in the active-training task (same data as in pseudocolor plot). (C) Mean number of investigations of non-task-related odor tubes in the home cage for mice exposed to the same odorants as in the active-training task (blue diamonds), mice exposed to odorants mismatched from the active-training odorants (rust squares) and mice exposed to unscented tubes (green triangles).
