- Abstract
Independent Component Analysis (ICA) is used in this paper to study the brain signals of patients with Amyotrophic Lateral Sclerosis (ALS) in the EEGLAB toolbox. Electroencephalography (EEG) signals are recorded in unipolar mode, wherein the Cz electrode is selected as the reference electrode. Therefore, it is expected that the independent components of brain signals can be analyzed while the patient moves his/her hands, and the event-related potential of the process can be separated as an independent component using the maximum value of its variance. The results show that by using ICA in analyzing the brain signals during hand movement, different brain activities that are related to the moving process can be separated. One of the major problems in analyzing brain activity is feature extraction. In this study, the absolute value of the amplitude, variance, θ (3–8 Hz) and α (8–13 Hz) band average power and the power of frequency components inα and θ bands are considered as the features. The results show that the features of the independent components present more accurate diagnosis compared to the brain signals characteristics. These features can be used in brain-computer interface systems to determine SMR in patients with ALS.
