This edition of the volume โAdvances in Intelligent Systems and Computingโ presents the proceedings of the 3rd International Scientific Conference BCI. The event was held at Opole University of Technology in Poland on 13 and 14 March 2018. Since 2014 the conference has taken place every two years at the Universityโs Faculty of Electrical Engineering, Automatic Control and Informatics. The conference focused on the issues relating to new trends in modern brainโcomputer interfaces (BCI) and control engineering, including neurobiologyโneurosurgery, cognitive scienceโbioethics, biophysicsโbiochemistry, modelingโneuroinformatics, BCI technology, biomedical engineering, control and robotics, computer engineering and neurorehabilitationโbiofeedback.In addition to paper presentations, the scientific program also included a number of practical demonstrations covering, for example, the on-line control of mobile robot and unmanned aerial vehicle using the BCI technology.
