Best Answer

Approximately three quarters of the fibers of the cortex cross over in the medulla and extend down the cord. This occurred early in embryonic development and was caused by chemical signals produced by genes. No one really knows why except to guess that this is sort of a back up mechanism since all fibers do not cross over.

At the left side of the brain is the seat of language and processes in a logical and sequential order. The right side is more visual and processes intuitively, holistically, and randomly.

There are connections between the two sides. Injury on the left affects the right but with therapy that can be overcome.
