Abstract

An investigation of sine-modulated light (SML) as a stimulus for visual evoked responses and alpha rhythm feedback (ARF) is reported. The development of a multifunctional EEG research system (EEGRS) and EEG information analysis and management system (EIAMS) and eight experiments on SML and ARF are discussed. The EEGRS consists of a programmable, multifunctional, dual-channel stimulus generator, a transducer, an EEG signal sampler and amplifier, and a system controller. In the experiments, the visual evoked response is recorded and inserted into the EEG database embedded in EIAMS. Then it is processed, transformed, displayed and statistically analyzed. The results show that SML and ARF can stabilize the alpha frequency and increase the alpha component.<>
