What is an EEG?
Electroencephalogram (EEG) A record of the tiny electrical impulses produced by the brain's activity. By measuring characteristic wave patterns, the EEG can help diagnose certain conditions of the brain. Mentioned in: Delirium, Head Injury, Sleep Disorders. Gale Encyclopedia of Medicine.
What is an EEG?
An EEG records the electrical activity of your brain via electrodes affixed to your scalp. EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other seizure disorders.
Why is EEG used in a coma?
A continuous EEG is used to help find the right level of anesthesia for someone in a medically induced coma.
How are EEG electrodes connected?
In a high-density EEG, shown here, the electrodes are closely spaced together. The electrodes are connected to the EEG machine with wires. Some people wear an elastic cap fitted with electrodes, instead of having the adhesive applied to their scalps. You'll feel little or no discomfort during an EEG.
Why do we use EEG?
An EEG might also be helpful for diagnosing or treating the following disorders: An EEG might also be used to confirm brain death in someone in a persistent coma.

Here are some things you can expect to happen during an EEG: A technician measures your head and marks your scalp with a special pencil to indicate where to attach the electrodes. Those spots on your scalp might be scrubbed with a gritty cream to improve the quality of the recording.
What is the test that shows the activity of the brain?
An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp. Your brain cells communicate via electrical impulses and are active all the time, even when you're asleep. This activity shows up as wavy lines on an EEG recording.

Scientific definitions for electroencephalogram
A graphic record of brain waves representing electrical activity in the brain, used especially in the diagnosis of seizures and other neurological disorders.♦ The instrument used to record an electroencephalogram is called an electroencephalograph.It generates a record of the electrical activity of the brain by measuring electric signals using a set of electrodes attached to the scalp that act as transducers.
Cultural definitions for electroencephalogram
A written recording of the electrical activity of the brain. Electroencephalograms are useful in studying and detecting brain disorders.
What Is an Electroencephalogram?
An electroencephalogram is a recording of the electrical activity of the brain. The human brain is made up of approximately 100 billion cells. These cells, called neurons, use electrical and chemical signals to communicate with each other.
How EEGs Are Recorded
Hans Berger (1873-1941), a German psychiatrist, is credited with recording the first EEGs in humans. Although Berger's work was dismissed when it was published in 1929, the EEG was eventually accepted after other scientists confirmed Berger's claims. Now EEGs are routinely used for research and medical diagnosis.
How EEGs Are Used in Sleep Research
EEGs are performed by researchers to study the brain and by clinicians to diagnosis brain dysfunction. One area of research in which EEGs have been widely used is in the study of sleep. We often think of sleep as an all-or-none phenomenon. Either you are asleep or you are awake.

Overview
Why It's Done
- An EEG can determine changes in brain activity that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder. An EEGmight also be helpful for diagnosing or treating the following disorders: 1. Brain tumor 2. Brain damage from head injury 3. Brain dysfunction that can have a variety of causes (encephalopathy) 4. Inflammation of the brain (en…
Risks
- EEGsare safe and painless. Sometimes seizures are intentionally triggered in people with epilepsy during the test, but appropriate medical care is provided if needed.
How You Prepare
- Food and medications
1. Avoid anything with caffeine on the day of the test because it can affect the test results. 2. Take your usual medications unless instructed otherwise. - Other precautions
1. Wash your hair the night before or the day of the test, but don't use conditioners, hair creams, sprays or styling gels. Hair products can make it harder for the sticky patches that hold the electrodes to adhere to your scalp. 2. If you're supposed to sleep during your EEGtest, your doct…
What You Can Expect
- During the test
You'll feel little or no discomfort during an EEG. The electrodes don't transmit any sensations. They just record your brain waves. Here are some things you can expect to happen during an EEG: 1. A technician measures your head and marks your scalpwith a special pencil to indicate wher… - After the test
The technician removes the electrodes or cap. If you had no sedative, you should feel no side effects after the procedure, and you can return to your normal routine. If you used a sedative, it will take time for the medication to begin to wear off. Arrange to have someone drive you home. …
Results
- Doctors trained to analyze EEGs interpret the recording and send the results to the doctor who ordered the EEG. Your doctor might schedule an office appointment to discuss the results of the test. If possible, bring along a family member or friend to the appointment to help you remember the information you're given. Write down questions to ask your doctor, such as: 1. Based on the r…
