De La Pava Panche et al. [[4]] estimated directed phase-amplitude interactions from EEG data through kernel-based phase transfer entropy. Therefore, signal processing techniques have been applied to cancel artifacts and reduce noise, increasing the signal quality for subsequent analysis. Electrocardiogram (ECG), electrodermal activity (EDA), and electromyogram (EMG) signals were considered. [Extracted from the article]
