Exploring the Cognitive Impact of Optical Illusions on EEG Signals

This study explores the impact of visual illusions on brain activity by employing electroencephalography (EEG) as a noninvasive tool to monitor neural responses. EEG allows real-time monitoring of brain activity, distinguishing frequency bands associated with distinct states of consciousness. The study investigates how optical illusions influence emotional components of perception, utilizing EEG at rest and exposure to illusions of varying difficulty levels (easy, medium, and hard). Peak-to-peak amplitudes were observed for each level. Preprocessing procedures, including artifact removal and filtering were used to enhanced EEG data quality. Spectral analysis reveals brainwave patterns (delta, theta, alpha, beta, and gamma waves) under different conditions, shedding light on the neural correlates of visual perception and cognitive processing.
