AP PSYCHOLOGY

Detailed explanation-1: -An electroencephalogram (EEG) is a test that measures electrical activity in the brain using small, metal discs (electrodes) attached to the scalp. Brain cells communicate via electrical impulses and are active all the time, even during asleep. This activity shows up as wavy lines on an EEG recording.

Detailed explanation-2: -This study is generally done by an EEG technician and may take approximately 45 minutes to 2 hours. If you are being evaluated for a sleep disorder, the EEG may be done while you are asleep.

Detailed explanation-3: -The main use of an EEG is to detect and investigate epilepsy, a condition that causes repeated seizures. An EEG will help your doctor identify the type of epilepsy you have, what may be triggering your seizures and how best to treat you. Less often, an EEG may be used to investigate other problems, such as: dementia.

Detailed explanation-4: -Recording the EEG during drowsiness and sleep can be useful to identify brain activity which may not be present while your child is awake. It can be carried out on patients of all ages and abilities, making it a good way to get an overall view of the function of the brain.
