Detailed explanation-1: -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-2: -An EEG machine is a device that records the electrical activity of the brain. It contain electrodes that can detect brain activity when placed on a subject’s scalp. The electrodes record the brain wave patterns and the EEG machine sends the data to a computer or cloud server.
Detailed explanation-3: -The EEG is used to evaluate several types of brain disorders. When epilepsy is present, seizure activity will appear as rapid spiking waves on the EEG. People with lesions of their brain, which can result from tumors or stroke, may have unusually slow EEG waves, depending on the size and the location of the lesion.
