The use of a mouse model in evaluating changes in intelligence level. The mouse model is a high-intelligence-level mouse model. The chromosome of a mouse from the high-intelligence-level mouse model at least contains all or part of the chromosome 1 derived from a wild-type mouse. The evaluation includes the implementation of tests selected from the following group: an opening test, a sucrose preference test, a water maze test, a space probing Y maze test, an active avoidance Y maze test and a fatigue rotation rod test.
