What does an electroencephalogram record?

What does an electroencephalogram record?

An electroencephalogram (EEG) is a recording of brain activity. During the test, small sensors are attached to the scalp to pick up the electrical signals produced when brain cells send messages to each other. These signals are recorded by a machine and are looked at by a doctor later to see if they’re unusual.

What does an electroencephalogram measure and what information does it provide?

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.

When would you use an electroencephalogram?

Most EEGs are done to diagnose and monitor seizure disorders. EEGs also can identify causes of other problems, such as sleep disorders and changes in behavior. They’re sometimes used to evaluate brain activity after a severe head injury or before a heart transplant or liver transplant.

What do you need to know about an electroencephalogram?

What do I need to know about an electroencephalogram (EEG)? An EEG is a test that measures the electrical activity in your brain. It can help healthcare providers decide what treatments you need. An EEG can also help diagnose or monitor any of the following:

What is the abbreviation for electroencephalograph ( EEG )?

Since the word electroencephalogram can be a mouthful to say and tedious to write, it is usually just abbreviated to EEG. The equipment that detects and records the electrical activity of the brain is called an electroencephalograph. The printed record of the brain’s activity is an electroencephalogram.

Why do I have a seizure during the electroencephalogram test?

Bright lights or loud noises may cause you to have a seizure during the test. Healthcare providers may give you medicine to control or stop your seizure. They will also protect you from injury. You may be given medicine to help you sleep during the test.

Do you feel pain during an electroencephalogram test?

You will not feel pain during the test. Healthcare providers will ask you to lie still, and not talk during the test. A healthcare provider will put gel or cream on your scalp. He will place small discs in different places on your head. The discs will be connected to wires and a monitor.

How is electroencephalography used to record brain activity?

Electroencephalography, technique for recording and interpreting the electrical activity of the brain. The nerve cells of the brain generate electrical impulses that fluctuate rhythmically in distinct patterns.

Which is the dominant wave in the electroencephalogram?

The electroencephalogram (EEG) provides a record of the brain’s electrical activity. The normal human EEG displays continuous rhythmic activity in the form of wavelike patterns varying in frequency and amplitude. The dominant rhythm is the alpha wave, which reaches its maximum frequency in adolescence and begins….
