EEG (electroencephalogram): An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, flat 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.

An electroencephalogram (EEG) is an essential tool that studies the brain's electrical activity. Despite the development of more advanced imaging techniques, EEG remains the essential paraclinical tool for seizure evaluation. It is primarily used to assess seizures and conditions that may mimic seizures. It is also useful to classify seizure types, assess comatose patients in the intensive

The EEG is an electrophysiological technique for the recording of electrical activity arising from the human brain. Given its exquisite temporal sensitivity, the main utility of EEG is in the evaluation of dynamic cerebral functioning. EEG is particularly useful for evaluating patients with suspected seizures, epilepsy, and unusual spells.

The electroencephalogram (EEG) is a measure of brain waves. It is a readily available test that provides evidence of how the brain functions over time. The EEG is used in the evaluation of brain disorders. Most commonly it is used to show the type and location of the activity in the brain during a seizure. It also is used to evaluate people who

An EEG may also be used to determine the overall electrical activity of the brain. For example, it may be used to evaluate trauma, drug intoxication, or the extent of brain damage in a person who is in a coma. Depending on where the injury is, an EEG is one test of many to help decide brain death in young children.

In an EEG, the electrodes are placed on specific points on your head and connected to an EEG machine with cables. The electrodes measure the activity of the brain and display it as a graph on a screen. Many organs produce electrical signals that can be detected and measured using various techniques. One well-known example is the

EEG is also used to: Evaluate problems with sleep ( sleep disorders) Monitor the brain during brain surgery. An EEG may be done to show that the brain has no activity, in the case of someone who is in a deep coma. It can be helpful when trying to decide if a person is brain dead. EEG cannot be used to measure intelligence.

Artifacts are common during the wakeful EEG, and one of the first hurdles of EEG interpretation is distinguishing these from cerebral signal. Most notable is the presence of low-amplitude, high-frequency activity arising from scalp muscles, often frontally dominant but seen throughout the tracing.
