Localizing oscillatory sources in a brain by MEG data during cognitive activity

The present work demonstrates the features and basic steps of applying the Dynamic Imaging of Coherent Sources (DICS) technique for Localizing oscillatory sources in a brain by MEG data during cognitive activity. As the example, we consider the problem of identification of the sources responsible for producing this oscillatory activity registering in the MEG experiment during the visual processing in a brain. The DICS technique has been shown to be effective in terms of localizing a region of activity in a brain related to cognitive processes. It revealed the areas in the occipital part of the brain that are responsible for processing visual stimuli. This approach allows one to obtain additional important information in the analysis of MEG data.
