Science has already established the fact that the brain is the body's command center. Everything you say, do and think about involves the power and function of the brain.
This central organ can be broken down into two different regions or hemispheres (left and right), each of which performs different functions including balance, speech, and movement. Any damage to a particular area of the brain can affect the function it controls. That would lead to symptoms like difficulty speaking, loss of concentration, or loss of movement.
The brain's left hemisphere controls the sensory and motor functions of the right side of the human body. It is also in charge of logical and scientific functions like the understanding of spoke and written language, reasoning, and number skills. The brain's right hemisphere controls the left side of the body's sensory and motor functions. The brain's right side takes care of decorative features like insight, art awareness, and music.
