2.3.1. Electroencephalography Recording
MKS
To acquire the data, we employed a 48-channel NVX-52 amplifier (MKS, Zelenograd, Russia). EEG signals were captured using 32 standard Ag/AgCl electrodes positioned in accordance with the international “10-10” system. The earlobe electrodes served as references, while the grounding electrode was positioned on the forehead. Electrode impedance was maintained below 15 k
