The brain is an incredible collection of lobes, ventricles, and systems, all working together to enable you to function. Click on the pictures on the right to see the different anatomy of the brain.
The frontal lobes of the cerebral cortex lie under the forehead. They control planning, reasoning, movement, and some aspects of speech. Here in the largest of the cerebrum's four lobes, most purposeful behavior occurs. The frontal lobes are connected with emotions and the limbic system operations.
The temporal lobes lie at the sides of the head above the ears. They perform several functions, including th hearing, speech perception, and some kinds of memory. The auditory center, part of the temporal cortex about the size of a poker chip, processes nerve impulses from the ears. In about 90 percent of rigt-handed people and 70 percent of left-handed people, the centers for spoken language lie in the left temporal lobe.
The parietal lobe at the top of the head receives data from the skin. Nuerons (nerve cells) there process touch and sensation information, including pain and the position of the body in space. Sensory processing communicates closely with the primary motor area, which lies just forward of the parietal lobe and controls voluntary action.
The occipital lobe lies at the back of the head just above the cerebellum. It processes and interprets sensory information from the eyes. Because the occipital lobe controls sight, it is often called the visual cortex. Damage to the occipital lobe can cause blindness even if there is nothing wrong with the eyes or the visual system.
Between the brain stem and the rear of the cerebrum lies the cerebellum, the area of the brain that controls posture, balance, and cordination. While voluntary motion is managed in the motor cortex, the cerebellum takes over many learned, physical skills. Its actions explain why riding a bicycle or driving a car take effort at first, but becomes automatic with practice.
Sometimes called the "Reptilian Brain", the brain stem is the oldest and most basic brain region.
The brainstem is the region of the brain that connects the cerebrum with the spinal cord. It consists of the midbrain, medulla oblongata, and the pons.
The brainstem coordinates motor control signals sent from the brain to the body.
This brain region also controls life supporting autonomic functions of the peripheral nervous system. The fourth cerebral ventricle is located in the brainstem, posterior to the pons and medulla oblongata. This cerebrospinal fluid-filled ventricle is continuous with the cerebral aqueduct and the central canal of the spinal cord.
Function:
The brainstem controls several important functions of the body including:
Alertness
Arousal
Breathing
Blood Pressure Control
Digestion
Heart Rate
Other Autonomic Functions
