On performance base our brain has divided into two parts…that is

left brain

right brain

the functions left brain and right brain are different.  let us see the functionality of the  brain

Your brain is divided into two sides, called hemispheres

The right side of your brain controls the left side of your body, and the left side of your brain controls the right side of your body. Interesting, right? The two sides of your brain are similar to one another; for example, the part of your brain that tells your arms and legs to move is the same on the right and left – it just controls different sides of your body.


The left side of the brain is concerned with language, number skills, reasoning, scientific skills, spoken language and right-hand control. The left side is the hub of language, where you “assemble” the language (words and sentence structure) you want to communicate. This is not to say that the right side of your brain has no involvement with language; the two sides of your brain work together to perform functions such as understanding, reasoning and organizing language.

We know from patterns of brain damage (for example: stroke, traumatic brain injuries or brain tumors), that when the left side of the brain is damaged in the areas that have been associated with speech production and language comprehension, people present with Aphasia (difficulty comprehending and/or expressing language). These language difficulties are (in almost all situations) not seen if the same damage is done on the right side of the brain.  So we know that the left side of the brain is very important for language and understanding. Other functions of the left side of the brain are analytical, logic, and computation skills.

The right side of your brain is in charge of visual awareness, imagination, emotions, spatial abilities, face recognition, music awareness, 3D forms, interpreting social cues, and left-hand control. It performs some math, but only rough estimations and comparisons. The brain’s right side also helps us to comprehend visual imagery and make sense of what we see. It plays a role in language, particularly in interpreting context and a person’s tone, staying on topic in a conversation and organizing your thoughts and ideas.
