Evoked EEG response research indicates the potential for a usable brain actuated control system. Reduction of time lag is essential for the continued development of our subject training system, which has yielded results, but has certain limitations in the areas of response time and false feedback due to artifacts. We are presently investigating a Lock-in Amplifier System LAS to overcome these system limitations. Frequency and phase facile system capabilities as well as artifact rejection techniques are being developed for the LAS. This powerful tool should enable effective training by continuously supplying subjects with an indication of their EEG output at a reference frequency. The experimentalprototype system will be discussed. Visually evoked response, Loop closure, Electroencephalographic signals.
