Environment
This chapter discusses how environmental parameters influence the physiology and behavior of rats and thus the experimental outcome. It considers lighting, humidity, airflow, noise, cage construction, diet, and social opportunity. Maternal influences, age at weaning, animal care, exercise regimens, and enrichment are also discussed. These factors can induce changes in brain weight, cerebral vascularization, adrenal size, and body weight.
Keywords: laboratory rats, environmental factors, rat physiology, rat behavior, weaning, animal care, exercise regimens
