Fig. 3: Feature extraction from EEG data across brain areas and frequency bands.

(a) Data recording set up. (b) EEG data analysis. (c) Extraction of EEG features from 21 individual Brodmann Areas (BAs) across four frequency bands. (d) The feature extraction process results in a comprehensive set of 168 distinct EEG features. Part (a) of this figure was developed by the ATLAS illustrator Shared Resource at RPCCC, using the Adobe Illustrator software.
