Left Brain vs. Right Brain

Difference between Left Brain and Right Brain 

The brain, a part of the central nervous system, is formed by left and right hemispheres that are almost equal in size and function. However, they also perform special functions that are unique to each. Usually, the left hemisphere of the brain controls the human’s right side of the body and vice versa. Although one hemisphere may be more dominant than the other, we need both sides of our brain to work in order to function normally.

Functions of the Left Brain

Because they use their right hands more, right-handed people consider the left hemisphere of their brains, which control the right side of their bodies, as the dominant lobe. Those with left dominant brains are logical, sequential, rational, analytical, objective, and looks at things as parts rather than as a whole.

Functions of the Right Brain

Left-handed people have their right brains as their dominant lobe. These people are generally random, intuitive, holistic synthesizers, subjective, and look at things as a whole rather than its parts.

Although each side of the brain has its own special functions, there are some organs that require both of them in order to work. Also, if one side of the brain isn’t working, the opposite side of the body may be paralyzed. It is therefore important that both sides are healthy and working.

In summary:

  • The left hemisphere of the brain controls the human’s right side of the body and vice versa
  • Right-handed people have left dominant lobes while left-handed people have right dominant lobes
  • People with left dominant lobes are logical, sequential, rational, analytical, objective, and looks at things as parts rather than as a whole
  • People with right dominant lobes are random, intuitive, holistic synthesizers, subjective, and looks at things as a whole rather than its parts
  • Some organs are controlled by both the left and right sides of the brain
