Dynamic imaging of coherent sources

WebDec 10, 2024 · In fact, the DICS (“Dynamic Imaging of Coherent Sources”) algorithm was specifically formulated in order to localize sources coherent with some (external) signal. In this example, we are going to use the DICS algorithm to estimate the activity of the neuronal sources and to simultaneously estimate the coherence with the EMG. WebAug 4, 2012 · Dynamic imaging of coherent sources (DICS) is one of these solutions. DICS is a source analysis method which is able to detect brain regions that are coherent with each other and a reference signal or region (Gross et al. 2001 ).
