The brain is a highly specialized organ. It serves as the control center for functions of the body and allows us to cope with our environment. Words, actions, thoughts, and feelings are centered in the brain. It is so complex that some theorists believe we will never be able to fully understand it. We do, however, know that each part of the brain has a specific, important function, often a profoundly important function, and each part contributes to the healthy functioning of our body.
The location of tumors in the brain is one of the factors that determines how a brain tumor affects an individual's functioning and what symptoms the tumor causes. Click the link to learn more about brain anatomy in ourInteractive Tour of the Brain or refer to the short glossary below.
Cerebrum is the largest part of the brain and is associated with conscious thought, movement and sensation. It consists of two halves, each controlling the opposite side of the body. The halves are connected by the corpus callosum, which delivers messages between them. Four lobes make up the cerebrum: the frontal, temporal, parietal, and occipital lobes.
Frontal Lobe is one of the four lobes of the cerebral hemisphere. It controls attention, behavior, abstract thinking, problem solving, creative thought, emotion, intellect, initiative, judgment, coordinated movements, muscle movements, smell, physical reactions, and personality.
Parietal Lobe is one of the four lobes of the cerebral hemisphere. It controls tactile sensation, response to internal stimuli, sensory comprehension, some language, reading, and some visual functions.
Sensory cortex is located in the front part of the parietal lobe, or in other words, the middle area of the brain. The sensory cortex receives information from the spinal cord about the sense of touch, pressure, pain, and the perception of the position of body parts and their movements.
Motor cortex is an area located in the middle, top part of the brain that helps control movement in various parts of the body.
Temporal lobe is one of the four lobes of the cerebral hemisphere of the cerebral hemisphere. It controls auditory and visual memories, language, some hearing and speech, language, plus some behavior.
Wernicke's Area is part of the temporal lobe that surrounds the auditory cortex and is thought to be essential for understanding and formulating speech. Damage in Wernicke's area causes deficits in understanding spoken language.
Occipital Lobe is one of the four lobes of the cerebral hemisphere. It is located in the back of the head and controls vision.
Broca's Area is located in the opercular and triangular sections of the inferior frontal gyrus. The function of this area is the understanding of language, speech, and the control of facial neurons.
