Multivariate coherence decomposition: a simulation study.
This paper presented a method, termed MVCCD<inf>FD</inf>(Multivariate coherence decomposition), for mapping coherent brain sources at given frequencies. By calculating averaged coherence over all pairs of channels, we can know at which frequencies there are strong coherence. And then, by utilizing MVCCD<inf>FD</inf>to corresponding frequencies we can get the 2D distributions of coherent sources at given frequencies. Computer Simulation shows that this method can identify the coherent brain sources at different frequencies.
