The brain is divided into three main parts: the forebrain, midbrain and hindbrain. The three parts work together, but they perform independent functions. The cerebrum is the largest part of the brain, and it fills most of the forebrain.
The cerebrum shares the forebrain space with the hypothalamus and thalamus, part of the limbic system. The amygdala and hippocampus are also located in the cerebrum.
The midbrain, along with the pons and medulla, is part of the brain stem. It helps the brain regulate basic life functions, including eye movement and hearing.
The hindbrain consists of the cerebellum, medulla and pons. Like the cerebrum, the cerebellum has two hemispheres. It controls posture and movement of the body.
