Cerebrum:

The cerebrum, also known as the telencephalon, is the largest and most highly developed part of the human brain. It encompasses about two-thirds of the brain mass and lies over and around most of the structures of the brain. The outer portion (1.5mm to 5mm) of the cerebrum is covered by a thin layer of gray tissue called the cerebral cortex. The cerebrum is divided into right and left hemispheres that are connected by the corpus callosum. Each hemisphere is in turn divided into four lobes. The cerebrum or telencephalon, along with the diencephalon comprise the two major divisions of prosencephalon (forebrain).

Function:

The cerebrum is involved in several functions of the body including:
  • Determining Intelligence
  • Determining Personality
  • Thinking
  • Perceiving
  • Producing and Understanding Language
  • Interpretation of Sensory Impulses
  • Motor Function
  • Planning and Organization
  • Touch Sensation

Location:

Directionally, the cerebrum and the cortex that covers it is the uppermost part of the brain. It is the anterior portion of the forebrain and is superior to other brain structures such as the pons, cerebellum and medulla oblongata.
