The accumulated knowledge about normal intracranial EEG activity (iEEG) is very low. This is because patients with refractory focal epilepsies are the onlyhuman subjects where the iEEG is allowed. At the beginning of 2018, the firstiEEG normal activity atlas https://mni openieegatlas.research.mcgill.ca //] waspublished. The atlas provides dense coverage of all cortical regions in acommon stereotactic space, which allows direct comparisons of EEG between subjects. In this work we analyze the oscillatory and scaling properties of nonoscillatory components of iEEG signals in normal and waking states, such asthe spectral power, as well as scaling exponents and avalanche distributions (not shown here) using the data from the mentioned atlas.
