Introduction
EEG is a test that uses small metal discs to determine the brain’s electrical activity. Also known as electrodes, the small metal discs are usually attached to the scalp when using the EEG.
Brain cells remain active all the time and communicate through electrical impulses, whether sleeping, resting or doing everyday tasks. The electrical impulses appear on the AI EEG recording machine screen as wavy lines, allowing medical experts to diagnose diseases such as epilepsy and other brain disorders.
What is an EEG Cap?
EEG is a short form for electroencephalogram – a brain activity recording. Electroencephalogram is a painless test that involves small sensors attached to the scalp.
These sensors are designed to pick up electrical signals the brain produces. While a machine records these signals, the doctor examines them. Highly trained medical experts, known as clinical neurophysiologists, perform the procedure during a hospital visit.
How Does an EEG Work?
An EEG works in different ways and is available in various types. Before the medical examination begins, the experts will clean the scalp, and approximately 20 small sensors (electrodes) will be attached to it using a special paste or glue. The tiny sensors have wires that connect them to an AI recording machine.
When undergoing the test, you need to lie down or sit. Routine EEG recordings take a minimum of 20 minutes. However, a typical appointment lasts about an hour, which includes preparation and finalising time. Other types of EEG include routine, sleep or sleep-deprived, video telemetry, ambulatory, and invasive EEG-telemetry.
Why is the EEG Test Done?
The EEG test is done to establish a brain activity that might help diagnose a wide range of brain disorders, from epilepsy to sleep disorders. EEG might also help diagnose and treat Creutzfeldt-Jakob disease, stroke, herpes encephalitis, brain dysfunction, brain damage from injuries and brain tumours. Medical experts also use EEG tests to confirm brain death in individuals who’re in a coma.
Are there any EEG Test Risks?
EEG tests are usually painless and safe. Sometimes, the test triggers seizures in individuals with epilepsy during the test. Experts provide appropriate medical care if needed.

In conclusion, EEG caps play a pivotal role in the field of neuroscience, enabling researchers and healthcare professionals to delve into the intricacies of the human brain. These caps, equipped with multiple electrodes, work by capturing and recording the electrical activity generated by the brain’s neurons.
Throughout our exploration, we have gained insight into the functioning of EEG caps and their significance in various domains, such as cognitive research, clinical diagnostics, and brain-computer interfaces. The electrodes embedded in the cap detect and measure the electrical signals produced by neurons firing in specific regions of the brain.
