The electrodes are connected by wires to a speaker and recording machine that changes the electrical signals into patterns of wavy lines that can be seen on a computer. The electrodes are placed all over the patient’s scalp and are held in place with a sticky paste. The disks are held in place with a sticky paste. The test is done by an EEG specialist in a physician’s office or at a hospital or laboratory.įlat metal disks called electrodes are placed all over the patient’s scalp. The amount and pattern of electrical activity is important in diagnosing seizure disorders.īrain cells communicate with each other by producing tiny electrical signals, called impulses. An EEG is done by placing electrodes, flat metal disks that are small sensors, on a person’s scalp to detect the electrical impulses moving through the brain.Īn EEG is often used to help determine the presence and cause of seizures. Contact Usįor further information, please call 215.345.2335, Monday through Friday from 7:30 am to 3:30 pm.An electroencephalogram (EEG) is a procedure that measures the electrical impulses in the brain. We would like to make your child's EEG testing as comfortable and pleasant as possible. Your doctor will talk with you about the results and answer any questions you may have. Why is an EEG Done?Īn EEG can help your doctor diagnose and monitor seizures, observe sleep patterns and check brain function after a head trauma.ĮEG is useful in diagnosing and monitoring epilepsy and other conditions that affect brainwaves.
Ask your physician if any special instructions are needed to prepare for your test. Generally, no special preparation is needed however, there are specialized EEG studies which may be done under different conditions. Your doctor should give you any instructions about what is needed to prepare for your EEG. The electrodes connect to a piece of equipment called the EEG amplifier, which tracks and records the brain's electrical signals, then sends them to a computer where they can be analyzed. An electroencephalogram (EEG) is a diagnostic test that detects electrical activity in the brain using electrodes (small, flat metal discs) attached to the scalp. In 1924, Hans Berger used his ordinary radio equipment to amplify the brain's electrical activity measured on the scalp. These signals (also called brainwaves) can be recorded through the scalp.
The brain works by a series of nerve impulses which cause electrical signals. In 1914, Napoleon Cybulski and Jelenska-Macieszyna photographed EEG-recordings of experimentally induced seizures. An electroencephalogram (EEG) is a test that looks at the function of the brain. The technologist will ask you to lie down or sit in a chair, then attach electrodes to various places on your scalp. Pravdich-Neminsky published the first animal EEG and the evoked potential of the mammalian (dog).
This is detected via small metal discs called electrodes that are positioned in.
Small, round discs with wires (electrodes) are. The test takes about 30 minutes to complete. An EEG is a measurement of the continuous electrical activity of the brain. An electroencephalogram (EEG) is a test that measures the electrical activity in the brain (brain waves). It's primarily done to diagnose epilepsy, but has other uses as well. The non-invasive, outpatient procedure does not hurt and you should be comfortable. An electroencephalogram (EEG) detects abnormal brain waves that cause seizures. The test is usually ordered by a neurologist or a sleep medicine physician. Electroencephalogram (EEG) What is an EEG?Īn Electroencephalogram (EEG) is a medical test performed at Doylestown Hospital that measures and records brain wave patterns to identify problems with the brain's electrical activity.Ī safe and fast way to record brain activity, the EEG results help physicians understand how the brain is working electrically and look for abnormalities.
