Detailed explanation-1: -an amplified recording of the waves of electrical activity that sweep across the brain’s surface. These waves are measured by electrodes placed on the scalp.
Detailed explanation-2: -EEG. The electroencephalogram (EEG) is a recording of the electrical activity of the brain from the scalp. The recorded waveforms reflect the cortical electrical activity.
Detailed explanation-3: -An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain.
Detailed explanation-4: -An EEG records the electrical activity of the brain via electrodes affixed to the scalp. EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other seizure disorders.
Detailed explanation-5: -An EEG can be used to help diagnose and monitor a number of conditions affecting the brain. It may help identify the cause of certain symptoms – such as seizures (fits) or memory problems – or find out more about a condition you’ve already been diagnosed with.
