Frontal lobe

The frontal lobe of the brain, the large part of the brain at the front of our heads, is involved in our personality characteristics and speech as well as sensory activity and movement.
Occipital lobe

The occipital lobe is the large part of the brain at the back of our heads. Its most important function is to control visual perception.
Parietal lobe

The parietal lobe, the middle part of the brain, helps us with identifying objects and spatial relationships, that is with locating ourselves in relation to other people and things. It is involved in interpreting pain and touch.
Cerebellum

The cerebellum, the back pact of the brain, has as its main function the control of balance, voluntary muscle activity and posture.
Temporal lobe

The temporal lobes, the sides of the brain, are involved with memory, auditory perception and our sense of smell.
Brainstem

The brainstem is the middle part of the brain and joins the spinal cord to the cerebrum and the cerebellum. It includes the medulla, which is the section that links the left and right sides of the brain to each other and the spinal cord. The medulla is the lowest part of the brainstem and is vitally important in controlling the heart and lungs and involuntary functions like breathing, salivation, coughing, eye movements, pain and other sensations, and hunger.
