**4. Conclusions**

This chapter aimed to achieve significant optimization of cortical visual responses, signal processing methods, and ML algorithms, as well as the accuracy and reliability of the superior multi-command SSVEP-based BCI system. New approaches have been explored using existing methods to develop an accurate, reliable, comfortable SSVEPbased BCI that can offer people with severe motor neuron diseases a communication

alternative using attention modulation without requiring neuromuscular activities or eye movements.

As a result, the following research objectives were achieved in this study:
