Brain Structure and Function

The three principal parts of the brain are the Cerebrum, and brainstem. The cerebrum consists of the right and left hemispheres and is the largest portion of the brain. It performs higher functions such as touch interpretation, vision and hearing, as well as speech, thought, emotion, learning and control of the movement. In the human body, the brain is the most important organ. It controls and coordinates actions and reacting, allows us to think and feel, and enables us, all things that make us human, to have memories and feelings.
