**6. Conclusion**

EEG emulation of control circuits is a new direction in EEG research. It was introduced in 2005 with the concept of a CNV flip-flop. However, after the Vidal's BCI challenge in 1973, the first explicit description of an EEG emulated electronic circuit was given in 1988. It was an EEG emulated switch, actually a Schmitt trigger, based on the EEG alpha rhythm. Recently in 2015 the EEG emulated demultiplexer and EEG emulated modem were described. This paper is a first review of this new direction in EEG research.
