Source Localization

Definition: Source localization is a technique used to determine the location of the neural generators that give rise to a particular brain signal, such as an electroencephalogram (EEG) or magnetoencephalogram (MEG) signal. In addition, use of fNIRS for source localization measures changes in blood oxygenation in the brain as an indirect measure of neural activity that can be used as prior information in solving the inverse problem. The importance of source localization is the understanding of the neural mechanisms underlying cognitive processes and provide insights into the different techniques that can be used for this purpose.Definition: Source localization is a technique used to determine the location of the neural generators that give rise to a particular brain signal, such as an electroencephalogram (EEG) or magnetoencephalogram (MEG) signal.
