Crossing the Midline

Crossing the midline refers to an imaginary line which runs down the center of the body and the ability to crossover with opposite appendages ie hands, feet.  Sound simple and confusing?  Think of the standard windmill exercise of touching the right hand to the left foot and vice versa.  That would be a classic example of crossing the midline.  This crossing the midline stuff is important for the brain in reading.

The brain is divided into two spheres, left side and right side with a sort of  bridge between the two called a corpus collosum, which wires everything together.  The real kicker is the right side of the brain controls the left side of the body while the left side of the brain controls the right side.  Add to the mix that we as humans seem to favor one side of our brain over the other.  You may have heard the phrase "left brain dominant" or "right brain dominant".  This refers to how an individual is influenced by the side of their brain which for whatever reason, is strongest.  Here's how it breaks down:

Left Side                                                                        Right Side
