Abstract

After being exposed to an enriched environment for 40 days, noradrenaline content was increased significantly in the parieto-temporo-occipital cortex, the cerebellum and the pons/medulla oblongata. In contrast, no changes were observed in serotonin or dopamine levels in these same regions.
