TEEG (electroencephalography, EEG) is a kind of single which we know human brain function active.BT (Biofeedback Therapy, BT) is based the method of EEG technology, focusing on the studies of human thoughts and emotions activities. We shall study new points that the two kinds of EEG technology are used simultaneously, to find the BT can be quantified abnormal EEG activities in mental illness, to provide the certain reference value in clinical. We found that BT can quantify β wave, θ wave and

... e abnormal phenomenon of traditional EEG. Therefore, based on the conventional examination of the traditional EEG in clinical, we used BT to further check. The results show not only to quantify the advantages of traditional EEG brain waves specific values occur, such as the specific data of fatigue (θ wave) and anxiety (β wave), but also abnormal phenomenon. Quantized data would become more intuitive, and to assess the clinical efficacy of treatment more scientific and objectivity. With the progress of research, people found the brain was a complex system. Not all of the diseases of the nervous system had abnormal EEG; some abnormal EEG had no brain lesions necessarily. So, EEG was only a secondary means of checking. Na S H and his research group [4] found that EEG was nonlinear dynamic parameters with comparing all kinds of EEG, as is marked the EEG would enter into the phase of quantitative research. Today, the analysis skill of
