What is the full form of EEG?
The EEG full form is Electroencephalogram. It is a process used to examine the electrical behavior of the brain. Neurons, or brain cells, communicate with one another by electrical impulses. EEG comprises a measurement of brain waves, which indicates how the brain functions over time. It identifies and records brain wave patterns generated by the brain’s electrical impulses.

- Tiny metal discs with thin wires that are labeled as electrodes are included with the testing device.
- The scalp-mounted electrodes provide signals to the computer in order to monitor the result.
- It provides a standard or known pattern for normal brain activity, but for aberrant brain activity, the pattern may be distorted or unrecognizable.
EEG Working principle
- The EEG process is non-invasive and painless.
- The electrodes attached to the scalp collect electrical activity within the brain from neurons and transmit it to a system where it is registered or shown as a series of lines on a computer monitor (running paper).
- The technician would remove the electrodes once the results were obtained.
- A doctor who specializes in the brain, such as a neurologist, can analyze your brain wave sequence recordings.
Why does the doctor recommend that the patient get an EEG?
EEG is performed to treat particular medical disorders or in the following instances:
- To diagnose and track disorders causing seizures.
- To detect sleep problems & epilepsy.
- To determine the origin of a number of different illnesses, such as sleep difficulties and behavioral abnormalities.
- To evaluate brain activity after a serious head injury or before a liver or heart transplant.
