A complex system of the mouse brain - selection for successful solution of a cognitive test

Abstract

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