Influence of “Enriched Environment” on Behavior and Neurogenesis in Mice Selected by Cognitive Trait
- 25 Downloads
Mice selected for high score in the extrapolation test (EX line) and kept under conditions of “enriched environment” for 3 months demonstrated changes in locomotor and exploratory activity and enhanced reaction to novelty. The relative brain weight was higher and neurogenesis in the hippocampal fascia dentate was more intensive in this group. In non-selected mice, the changes were similar, but insignificant in many cases.
