Changes in EEG measurements in intractable epilepsy patients with neurofeedback training

To assess the effects of neurofeedback on brain electrophysiology and to determine how biofeedback works, power spectral density (PSD) and approximate entropy (ApEn) analyses are applied to the EEGs of six patients with intractable epilepsy who received neurofeedback training. After sessions of treatment, the EEG sensorimotor rhythm to theta PSD ratio calculated from the C4 electrode site becomes larger than that before the treatment, which is consistent with the biofeedback protocol. The ApEn over 16-channel EEG recordings all increase to different degrees. Larger increases occur in channels located near the training position (C4). All these results suggest that these EEG measurements are new criteria that can be used to evaluate the effect of neurofeedback.     

控制论方法在生物学研究中的应用

控制论是第二次世界大战后出现的一门薪学科。它是由美国数学家诺伯·维纳(N.Wiener,1964—1964)提出的关于动物和机器中控制和通讯的科学。它是自动控制、电子技术、无线电通讯、神经生物学、数理逻辑、统计力学等多种学科和技术相互渗透的产物。它产生于本世纪四十年代,早在1943年维纳等人在发表《行为、目的和目的论》一文时就第一次把属于生物的有目的行为赋予机器,阐明了控制论的基本思想。
