Teaching, or even forcing, people to become ambidextrous is a practice that has been around for centuries. Some even claim that learned "cross dominance" can improve brain function. But as the science shows, not only is this not true, it may actually harm our neural development. Indeed, it wasn't too long ago that many parents forced their children to use their nondominant hands.

Lots of companies offer ambidexterity training that promises to improve cognitive power. But research shows there could be risks. C ould learning to write with both hands make your brain sharper and more speedy? Could training schoolchildren to use their non-dominant hands improve their exam results? Such claims have been popular for more than a century. Handedness — the preference for using one hand over another — is one of the deepest mysteries of neuroscience.

Do left-handed see different than right-handed people when looking at the same thing? The following experiment will answer the above question. Background Research.
After a left hemisphere stroke, you can optimize recovery by understanding the unique side effects that may occur. Although every stroke is different, there are known side effects that individuals are more likely to experience after a stroke on the left side of the brain. Below, you will learn about these side effects along with rehabilitation methods to help you regain lost function. A stroke occurs when the blood flow in the brain becomes blocked by either a clogged artery ischemic stroke or burst artery hemorrhagic stroke.
