The study by Greenough et al. (1990) found that the cerebellums of rats raised in a rich environment with lots of learning and motor behavior had more neuronal connections and dendrites compared to rats raised as "couch potatoes." This suggests that environmental enrichment can lead to greater neural complexity and connectivity in the brain.
