Orientierungsvermögen bei Mäusen - Versuche im Hochlabyrinth

The first scene in the film shows a mouse learning a labyrinth route with the aid of three `skeleton-keys` : drop shutters, scent trails trails, and echo effects. As each of these was removed, the mouse had to learn anew. In scene 2 (after 3 months) is covers the route without a mistake, all three aids having been removed. When angles (scene 3 and 4), path lengths (scene 5), and direction of turns (mirror-invertede, sence 6) were changed, both blind and seeing mice (subsequent scene) covered the route nearly without error straightaway, without having to learn anew : in the training labyrinth they had learned the "Gestalt" of theright way as transposable as, for instance, the letters of our alphabet.
