Brain Computer Interface (BCI) is one of the new emerging field in which a direct communication pathway is established between a human or animal brain and any outside or external device. The two way BCI’s allow the brain and the external devices to exchange signals in both the directions. But until today we have been successful in establishing one way BCI’s. In future, we will be able to use two way BCI’s effortlessly. The best is yet to come. In this chapter, an introduction to the BCI technology is given, the different signals generated by the brain are stated, also brain anatomy is explained. In addition, how are brain signals generated by the brain, how does BCI system work, a method to perform Electroencephalogram, how are those brain signals detected is explained and also BCI classes are stated and introduced.
