Abstract and Keywords
This chapter reviews the literature on environmental enrichment and specifically discusses its influence on the hippocampus of the brain. In animal models, the term “environmental enrichment” is used to describe a well-defined manipulation in which animals are exposed to a larger and more stimulating environment. This experience has been shown to have a powerful and positive impact on hippocampal cognition and neuroplasticity in animals. In humans, however, the translation of environmental enrichment is less clear. Despite the fact that humans live considerably more enriching lives compared to laboratory animals, studies have shown that training and expertise (such as exercise and spatial exploration) can lead to both functional and structural changes in the human brain. This chapter is a comprehensive review of environmental enrichment, drawing parallels between animal models and humans to present a more complete understanding of environmental enrichment.
