Power spectrum of the
electrocorticogram for the following groups: control (black), irradiation evaluated at 24 h (IR24; red) and at 90 days (IR90; blue).
The role of BCIs is to transfer commands by measuring various mental states using recording methods such as electroencephalography (EEG), magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), and
electrocorticogram (ECoG) [4].
This mental activity leads to changes of electrophysiological signals like the Electroencephalogram (EEG) or
Electrocorticogram (ECoG).
