DOI: 10.1016/j.compbiomed.2016.11.002
Abstract: Stochastic electroencephalogram (EEG) signals are known to be nonstationary and often multicomponential. Detecting and extracting their components may help clinicians to localize brain neurological dysfunctionalities for patients with motor control disorders due to the fact… read more here.
