The largest part of the human brain is the cerebrum.

Quick Scoop

  • The cerebrum makes up about 80–85% of the total mass of the human brain, forming the big, wrinkled upper portion seen in diagrams.
  • It is divided into two hemispheres (left and right), each further divided into lobes such as frontal, parietal, temporal, and occipital.
  • Most higher brain functions—like thinking, memory, voluntary movement, language, and conscious perception—are primarily handled by the cerebrum.

So if a multiple-choice question asks, “Which of the following is the largest part of the human brain?”, the correct answer is: Cerebrum.
