In studies at UC Berkeley in the 1970s, researchers placed laboratory mice in enriched environments containing mirrors, swings, ladders, little tunnels to run through, and so on. Later, when the researchers studied the brains of these highly stimulated mice, they found them to be much larger and more complex, and containing many more types of cells associated with intelligence, than the brains of mice that had not been stimulated in the same way. In a similar way, Holosync audio technology creates a super-enriched environment for your brain, encouraging new connections, complexity, and resiliency that otherwise would not develop.
