Eeg scan strengths and weaknesses
WebElectroencephalogram (EEG) is a test that looks at the function of the brain. The brain works by a series of nerve impulses, which cause electrical signals. These signals (also called brainwaves) can be recorded through the scalp. This page from Great Ormond Street Hospital (GOSH) explains the procedure for a Sleep EEG test and what to expect ...
