![]() ![]() Some of these patterns point to a strong possibility of epilepsy.Īn EEG test gives information about the electrical activity that is happening in your brain at the time the test is carried out. At different times, your brainwave patterns may be different.Ī highly trained specialist, called a clinical neurophysiologist, can recognise if your EEG test shows a brainwave pattern that is different to most other people. The EEG test can only show your brainwave patterns at the time the test is carried out. The electrical signals look like wavy lines that show your brainwave patterns. They don’t interfere with your brain and they don’t cause you any pain. They only pick up the electrical signals. The electrodes pick up the electrical signals from your brain and record them on a computer. Hair conditioner can help to remove the glue afterwards. After the electrodes are removed, you may still have a lot of glue in your hair. The electrodes are connected by wires to an EEG machine.Įlectrodes are attached using a special paste glue or paste. During an EEG test, small sensors, called electrodes, are placed on your scalp. Your brain constantly produces tiny electrical signals. An electroencephalogram (EEG) records activity in the brain. ![]()
