Quantitative Analysis of Different Consciousness Process Based on Multi-index Dynamic BEAM Technology

EEG is produced by the non-linear regularity system made up of many cerebral nerve cells. It is the only source from which we can know the electric activities of the brain based on non-invasion condition. BEAM is an imaging technology about brain function. It can be formed via interpolation calculation after converting EEG into an eigenvalue (index). This transformation is the core of BEAM, reflecting the reading ability on the EEG information. The majority of the existing BEAM adopts the analysis of power spectrum - a linear analysis technology which can only read the linear characteristics incompletely. Moreover, the method which only captures any part of EEG can not reflect the unstable dynamic characteristics of EEG. In considering of that, we have developed a new BEAM system for EEG detecting with wireless communication and EEG analysis based on multi-index. Have used this system, we studied 50 cases for different brain conscious activities, such as practicing Qigong and mental arithmetic. It had been said that this new BEAM technology was appropriate to the research of brain conscious activities. At one time we had got several experimental conclusions about practicing Qigong and mental arithmetic by quantitative analysis of experiment result.
