There are many applications that can help people with severe disabilities, video games, virtual reality and control of real things. EEG is the most widely used so that it forms the first element of the measurement and processing chain of the brain and computer interface. This electrical signal obtained by the electrodes placed on the skull or implanted in them, is able to record changes in brain electrical activity in real time. The project is designed by EEG. Most of the current methods cause events by external stimuli (audio, image, flash, touch). Other methods require volunteers to create an event to be detected (muscle contraction, eye movement or eyelids, or even a phantom movement). The aim of this project is to test the response of these different types of known neuroscience catalysts."
