The cerebrum is the largest part of the brain.
The cerebrum makes up 85% of the brain’s weight and is the main center of thinking. In addition, it controls the voluntary muscles and holds long-term and short-term memory, as well as managing reasoning and logic. The cerebrum is divided into two halves. The right half controls the left side of the body and vice versa. It is hypothesized that the right half is responsible for more abstract thought, while the left controls analytical thinking.
