Environmental enrichment. (A) Different kinds of rodent enrichment (picture from Satu Mering). (B) Super-enriched environment provides multiple and complex stimuli to the animals (modified from Sivenius et al., 2002). Enriched environment usually consists of large cage to provide spatial stimuli, ladders and running wheel for sensorimotor and motor exercise and social interactions of 6–8 animals. In addition, replaceable objects such as toys provide novelty, all of which can enhance brain plasticity leading to improved cognitive and sensorimotor recovery after brain insults.
