Electroencephalography (EEG) is a medical procedure that records electrical activity in the brain. However, this term can be quite a mouthful, which is why many people look for synonyms to simplify it. One such synonym is brain wave mapping, which is a more simplified term used for EEG scans. Another synonym for EEG is brainwave test, which is used to measure the electrical activity in a person's brain. Neuroimaging is another synonym that is used more broadly to describe the use of imaging technologies to extract information from the nervous system. Other synonyms include nerve conduction test, or even brain scan. All in all, there are plenty of synonyms that can be used to refer to EEG technology.
