Research has also shown that desirable low-stress rat environments retune their brains’ reward circuits, such as the nucleus accumbens. When animals are housed in their favored environments, the area of the nucleus accumbens that responds to appetitive experiences expands. Alternatively, when rats are housed in stressful contexts, the fear-generating zones of their nucleus accumbens expand. It is as if the brain is a piano the environment can tune."
