The objective of the study was to find evidence of the learning of spatial maps of albino mice in the three-dimensional space of a spatial learning and memory maze. Until now, both the discoverers of internal GPS (John O'Keefe, May-Britt Moser and Edvard Moser) and the learning theorists, including Edward Tolman and Charles Osgood, always carried out their studies on the plane and therefore on horizontal axes, Therefore, according to the objective, an observation instrument called Ascending Helical Maze (LHA) was designed with two components: LHA-A and LHA-B. By a simple experimental design (Fraisse, 1972) learning by instrumental conditioning in the LHA was observed, A: reinforced counterclockwise direction and B: unreinforced clockwise direction. Based on the results obtained, we conclude: 1) The LHA is a reliable and valid laboratory instrument according to the baseline established in this study, 2) The albino mouse adapts without preferential orientation due to the clockwise/anticlockwise direction of the LHA components ( intrinsic variable), 3) In the three-dimensional space of the LHA, the main effect was non-discriminative learning of the experimental variable, and the secondary effect was delayed discriminative learning, and, 4) Of 3, it is inferred that mice produce signal maps dominantly egocentric in non-discriminative learning and, a non-integrated map for delayed discriminative learning.
