Hemispheric asymmetry remains an important characteristic of the human brain, yet the mechanism behind this asymmetry remains unclear. The scalp EEG can serve as a reflection of the underlying nervous system's asymmetry, making it a potentially valuable tool in identifying abnormalities in brain activation. In the diagnosis of certain neurodegenerative diseases, brain asymmetry analysis has been utilized. Specifically, patients with mild cognitive impairment tend to exhibit a gradual decrease in brain asymmetry, while patients with Alzheimer's disease often experience an increase in asymmetry. Furthermore, the study of EEG-based frontal cortex asymmetry has been extensively pursued in neuropsychiatric diseases. Numerous reports have suggested that frontal alpha asymmetry (FAA) may serve as a neural marker for depression diagnosis, and have also explored the potential of altering this asymmetry as a means of treating depression
