A brain-computer interface (BCI) is a novel communication system that translates human thoughts or intentions into a control signal. It provides a new, nonmuscular communication channel that system developers can use in a variety of applications, such as assisting people with severe motor disabilities, supporting biffed-back training in people suffering form epilepsy, stroke or attentional deficit hyperactivity disorders (ADHD). It can changes the record in electrical potentials, magnetic fields, and metabolic supply when the activated neuron population exceeds some critical mass. Users in BCIs can explicitly manipulate their brain activity instead of motor movements to produce signals that control computers or communication devices. BCI exploits a strong characteristics of the EEG, the evoked potential, which reflects the immediate automatic responses of the brain to some external stimuli.
