WebApr 13, 2024 · The EEG-based BCI system facilitates a communication framework between the human brain and external intelligent devices by decoding the intrinsic cognitive patterns associated with different neural activities [ 29 ]. It takes in brain signals, analyses them, and translates them into computer-based control commands. WebIn general, drugs effects on the EEG are fairly predictable and include: no effect, accentuation of beta activity, background slowing with decreased amplitude and/or frequency of the alpha rhythm, intermixed theta and/or delta activity, decreased seizure activity, and lowering of the seizure threshold with increased spike and wave discharges.
