What is the major part of the human brain called?

The brain acts as the "command and control system" and controls various functions such as voluntary movements, balance, vital organs, circadian rhythms, endocrine glands and human behavior. The brain is divided into three major parts, the forebrain, midbrain, and hindbrain, which are the main regions that control different functions in the body.The cranial meninges consisting of dura mater, arachnoid and pia mater protect the brain and act as a protective layer. A deep cleft divides the cerebrum longitudinally into two halves, which are called the left and right cerebral hemispheres. The cerebral cortex contains motor areas, sensory areas, and large regions that are neither clearly sensory nor motor in function. These regions, called the association areas, are responsible for complex functions such as intersensory associations, memory and communication.
