Main experimental setup. PC1 was used to present stimuli and send markers, while the headbox was employed for preliminary filtering and amplification of EEG signals. The EEG amplifier further amplified and integrated the EEG signals, and PC2 was responsible for storing the EEG data and monitoring the entire experimental process.
