Right-left brain

What researchers have discovered about left and right brain thinking is not as simple as most people believe.  There’s a general belief that right-brained people are creative and left-brained people are logical, but this is not 100% true.  When the brain is examined in relationship to language, which is both creative and logical, studies have shown that both hemispheres are active.  It’s basically true that the logical parts of language such as grammar, vocabulary and literal meaning are mostly processed in the left brain, and the creative parts of the language such as intonation, emphasis and figurative meaning are processed in the right brain.  However, this is only true for 95% of right-handed people and 81% of left-handed people.  For that 5% of right-handed and 19% of left-handed people, this isn’t true.  Therefore, when you hear or read about the differences between right and left brain activity, you should understand that it’s only a generality and that there are lots of people for whom it’s not true.  Understanding this, however, let’s look at a typical right-handed person’s brain to see where different types of thinking are happening.

In a typical right-handed person, the right hemisphere is used for understanding new experiences and the left is used for routines or things you’ve done many times before.  The right brain is where creativity and imagination take place.  It’s also the center for holistic thinking, intuition, feelings and daydreaming.  The left brain is where logical and analytic thinking take place.  It’s also the center for mathematics, detailed thinking, reading and writing.

Generally, the left and right sides of our brains see the world in different ways, but they work together.  The right brain sees the whole picture and then concentrates on the details while the left brain starts with the details and puts them together to make the whole picture.  The left brain thinks in words and the right brain thinks in pictures.  It’s an interesting fact that the right brain controls the left part of the body, including the left eye, and the left brain controls the right side of the body, including the right eye.

We continue to learn more about the brain as time goes on, and many neuroscientists say that all this right-left brain information is outdated.  However, one thing remains true.  We need both parts of our brains to process the world around us.
