According to a recent study, activities such as learning to juggle actually boosts brain connections. Following an extensive 6-week practice period, the researchers observed changes in regions of the brain's white matter that are linked with reaching, grasping, and peripheral vision, regardless of how well the participants had learned to juggle.

From a cognitive point of view, it can therefore be inferred that learning something new and novel in addition to the time spent practicing is the key to changes in the brain. When brain training, it is essential to engage with new and varied exercises and to do it consistently over a period of time to realize the real changes and benefits.
