The brain is divided into left and right hemispheres. Each hemisphere controls its own unique set of activities or tasks.These hemispheres communicate with each other through a large bundle of nerve fibers called the corpus callosum, and through several smaller nerve pathways.

Left Hemisphere

The left side of the brain processes information more logically or sequentially. The left side of the brain is dominant in understanding and using language, including listening, reading, speaking and writing. It is involved in the memory for spoken and written messages, and plays a major role in the analysis of information.
