Location: Inside the skull.
Function: Controls all the other organs of the body and ensures they work together as a team.

What Can Go Wrong (Lots!)
Strokes: Brain attack, blood flow to the brain is restricted.
Mini-Stroke: A 'small' stroke, can indicate something bigger is brewing.
Hemorrhage: Bleeding in the brain, most common cause is stroke.
Aneurysm: Blood vessel in the brain bursts, causing internal bleeding.
Alzheimer's Disease: Causes confusion, loss of memory and speech problems.
Tumor: Cancer which starts in the brain or spreads from another part of the body.
Amnesia: Loss of memory, usually after a traumatic event.
Concussion: Injury to the head, causes loss of consciousness. Never let a concussed person fall asleep.
Epilepsy: Electrical activity of the brain is briefly interrupted resulting in a seizure.
Chemical Imbalance: Causes various types of depression. Effects of depression.
Headaches: From stress headaches to migraines.
Head And Face Disorders: Symptom checker.

The brain is where our consciousness is located, it allows us to think, learn and create. Information is primarily passed to and from the brain to the rest of the body, along the nerves of the spinal cord. The brain is divided into 4 main areas: the cerebrum, cerebellum, diencephalon and brain stem.
(1) Cerebrum: This is the largest part of the brain. It is split into two halves called hemispheres. The left hemisphere is used for analytical thinking and the right hemisphere helps us look at situations as a whole and make emotional judgments. The main parts of the cerebrum are:
Frontal lobe: Controls mood, muscle movement, planning for the future, setting goals and juggling priorities.
Parietal lobe: Processes information about temperature, touch, taste and movement coming from other parts of the body. Maths and reading are also processed here.
Pons: Important center for controlling breathing and cardiovascular function. It also helps to coordinate eye movement and balance.
Occipital lobe: Processes visual information for sight.
Temporal lobe: Processes memory, language and hearing.
(2) Cerebellum: This is the second biggest part of the brain. It coordinates muscles, allowing precise movements, balance and posture.
(3) Diencephalon: Contains the thalamus and hypothalamus. The thalamus is highly sensitive to incoming information, it lets the brain know what is happening outside of the body.The hypothalamus keeps conditions in the body regular. It regulates signals of thirst, hunger and body temperate. It also controls the release of hormones (little messengers) from the pituitary gland.
(4) Brain stem: Critical for regulating your heart beat, digestion, breathing and blood pressure - all unconscious activities that you are not aware of.
The brain is encased in three layers of membranes called meninges. Between each layer is a clear fluid which cushions the brain and helps protect it from infection.
Can I Live Without It?
No, without a brain, we die instantly. Furthermore any injury to the brain is permanent - despite medical advances doctors have not found a cure for brain damage. Once cells in the brain die, we permanently lose the function they are responsible for.
