Left handed people have different brains, then the right handed people...

Here is some research from Cornell University.  Areas of the brain can be different for left vs. right handed people or in between.  Since the 1970's, hundreds of studies have found that each hemisphere of the brain is home to a specific type of emotion.  Emotions linked to approaching the world such as, happiness, pride, anger lives in the left side of the brain.  While avoidance emotions such as disgust and fear is located in the right side of the brain.  This study shook everything up. Because the older studies used right hand dominate people, the left handed people were not included.  The researchers from the Cornell study, found that the left handed people could have all of the neurons reversed.  This is how they approach or avoid the world.  With the neural therapies that are around, mild electrical or magnetic stimulation, they are treating the part of the brain that encourage approach related emotions.  This could be damaging the left handed people, because the neural connections are reversed.

LENS neurofeedback does not use electrical or magnetic stimulation.  It uses a radio frequency that is a billion times lower than your cell phone.  This gentle, effective treatment allows the brain to heal on its own regardless of the neural placement.
