Electroencephalography (EEG) is a non-invasive neuroimaging technique that measures and records electrical activity in the brain. By placing electrodes on the scalp, EEG captures the fluctuations in voltage resulting from the collective activity of millions of neurons. This allows healthcare professionals to analyze brain function, diagnose neurological disorders, and monitor brain activity during various tasks or conditions.   What is a Brain Map in EEG? A brain map in EEG, also known as a quantitative EEG (qEEG) or brainwave mapping, refers to the process of analyzing EEG data to create visual representations of brain activity across different regions of the...
