Brain Computer-Interface (BCI) systems:
BCI systems utilize measurement of brain signals for communication or control via a computer-based signal processing, feature extraction, feature translation and device command scheme.
Real-time interaction with the computer and some form of feedback are key components of a BCI system.

Brain Computer-Interface (BCI) systems:
EEG-based systems to date have primarily utilized the following cortical signals:1. Slow Cortical Potentials (SCPs)2. Sensorimotor Rhythms (SMRs),
particularly
(8–12 Hz) and
(18–26 Hz) rhythms
3. P300 event-related potentials (ERPs)
