Abstract :
A Brain-Computer Interface (BCI) is a communication system in which messages or commands that a user wishes to convey pass not through the brain´s normal output pathways to the muscles but are instead extracted directly from brain signals. The basis for this is that mental activity (thought) can modify the bioelectrical brain activity and is therefore encoded in the recorded signals.
