I remember that study with mice where some mice were kept in a simple environment, while others had a rich environment with all kinds of things like a mouse wheel.
when the mice died, the simple environment mice had lots less interconnected neurons in their brain than the complex environment mice.
turns out it wasn't the complex environment that caused the brain development, it was the exercise wheel.
