dSPM
dSPM stands for dynamic Source Phương pháp Model. It is a method used in computational neuroscience for estimating the distribution of neural activity on the surface of the brain, typically from magnetoencephalography (MEG) or electroencephalography (EEG) data. dSPM is a type of distributed source localization technique, meaning it aims to find the locations and strengths of all active neural sources across the entire cortical surface, rather than assuming a small number of focal sources.
The core idea behind dSPM is to solve an inverse problem. Given the measured magnetic fields or
Compared to other distributed methods like MNE (Minimum Norm Estimate), dSPM provides estimates that are more
