“…Environmental enrichment (EE) may be defined as surroundings that provide animals with increased opportunity for social interaction, motor activity, and greater sensory stimulation than usually experienced in a standard laboratory environment.EE has been shown to consistently affect the behavior of animals, bringing about changes such as reduction of stress and anxiety-related activity [8][9][10] , improved performance in learning and memory tasks 8,11 , early onset of motor coordination and exploratory activity 11 , changes in maternal care 8 as well as resistance to addictive substances [12][13][14][15] .
