The Complex System of the Mouse Brain: Selection for Successful Solution of a Cognitive Test

This study provides a review of experimental research on selection in mice, which yielded positive results. The selection of mice was high (the task required mice to understand that an object that has become invisible still exists and can be found) and poor performance occurred in a cognitive test. The results we obtained revealed better short term memory in mice selected for high performance scores and that these mice also had higher performance in tests for novelty and attention. This suggests that differences between the mice used in the experiment are associated not only with cognitive abilities in tests, but also with more pronounced “executive functions.”
