What is the full form of EEG?
The full form of EEG is Electroencephalogram. It is a procedure that is carried out to evaluate the brain’s electrical behaviour. Brain cells, known as neurons, interact through electrical impulses with one another. EEG includes a brain wave metric, which is how the brain functions throughout time. It detects brain wave patterns of the brain’s electrical impulses and records them.
- Tiny metal discs with a fine wire that are labelled as electrodes arrive with the system that users perform the test.
- The electrodes are mounted on the scalp from where it passes signals to the computer to track the result.
- It produces a standard or identifiable pattern for familiar brain activity, but the pattern can be altered or unrecognizable for abnormal brain activity.
Working principle of EEG
- The EEG procedure is safe and pain-free.
- The electrodes mounted on the scalp collect electrical activity within your brain from the brain cells known as neurons and forward it to a system where they are seen as a series of lines registered or shown on a computer monitor (running paper).
- The technician would take the electrodes off after getting results.
- Your brain wave sequence recordings can be studied by a doctor specializing in the brain, like a neurologist.
Why does the doctor suggest the individual take the EEG test?
The EEG is carried out to treat the specific health conditions or in the following cases:
- To diagnose and track seizure diseases
- To detect sleep disorders & epilepsy
- To figure out the source of several other issues, like sleep disorders and behavioural changes issues.
- After a major head injury or before a liver or heart transplant, to determine brain activity.
