Dynamic imaging of coherent sources
WebMar 11, 2014 · The analysis tool used here is the dynamic imaging of coherent sources (DICS) for identifying the coherent brain sources at the pre-defined frequency band. DICS uses a spatial filter algorithm and estimates the tomographic coherence maps which are based on the realistic head models. There are two major constraints in this beamformer … WebDynamic imaging of coherent sources (DICS) uses a spatial filter to localize coherent brain regions and provides the time courses of their activity. Reference points for the computation of neural coupling may be based on brain areas of maximum power or other physiologically meaningful information, or they may be estimated starting from sensor ...
