| 1 | Visual Fixation Assessment in Patients with Disorders of Consciousness Based on Brain-Computer Interface显示文摘Visual fixation is an item in the visual function subscale of the Coma Recovery Scale-Revised(CRS-R).Sometimes clinicians using the behavioral scales find it difficult to detect because of the motor impairment in patients with disorders of consciousness(DOCs). Braincomputer interface(BCI) can be used to improve clinical assessment because it directly detects the brain response to an external stimulus in the absence of behavioral expression. In this study, we designed a BCI system to assist the visual fixation assessment of DOC patients. The results from 15 patients indicated that three showed visual fixation in both CRS-R and BCI assessments and one did not show such behavior in the CRS-R assessment but achieved significant online accuracy in the BCI assessment. The results revealed that electroencephalography-based BCI can detect the brain response for visual fixation. Therefore,the proposed BCI may provide a promising method for assisting behavioral assessment using the CRS-R. | Jun Xiao Jiahui Pan Yanbin He Qiuyou Xie Tianyou Yu Haiyun Huang Wei Lv Jiechun Zhang Ronghao Yu Yuanqing Li | 2018 | Neuroscience Bulletin2018，34，4： | 9 |
| 2 | Abnormal Effective Connectivity of the Anterior Forebrain Regions in Disorders of Consciousness显示文摘A number of studies have indicated that disorders of consciousness result from multifocal injuries as well as from the impaired functional and anatomical connectivity between various anterior forebrain regions.However, the specific causal mechanism linking these regions remains unclear. In this study, we used spectral dynamic causal modeling to assess how the effective connections(ECs) between various regions differ between individuals. Next, we used connectome-based predictive modeling to evaluate the performance of the ECs in predicting the clinical scores of DOC patients. We found increased ECs from the striatum to the globus pallidus as well as from the globus pallidus to the posterior cingulate cortex, and decreased ECs from the globus pallidus to the thalamus and from the medial prefrontal cortex to the striatum in DOC patients as compared to healthy controls.Prediction of the patients' outcome was effective using the negative ECs as features. In summary, the present study highlights a key role of the thalamo-basal ganglia-cortical loop in DOCs and supports the anterior forebrain mesocircuit hypothesis. Furthermore, EC could be potentially used to assess the consciousness level. | Ping Chen Qiuyou Xie Xiaoyan Wu Huiyuan Huang Wei Lv Lixiang Chen Yequn Guo Shufei Zhang Huiqing Hu You Wang Yangang Nie Ronghao Yu Ruiwang Huang | 2018 | Neuroscience Bulletin2018，34，4： | 4 |
| 3 | Finger or Light:Stimulation Sensitivity of Visual Startle in the Coma Recovery Scale-Revised for Disorders of Consciousness显示文摘Dear Editor,Coma,the vegetative state(VS),and the minimallyconscious state(MCS),often collectively referred to as disorders of consciousness(DOCs),typically occur after severe traumatic or non-traumatic brain injury^([1]).The boundary between awareness and unawareness remains elusive,making it difficult to correctly distinguish MCS from VS patients.It is possible to employ noninvasive neuroimaging techniques,such as functional MRI(f MRI)[2]to assess residual cognitive processing as well | Feng Zhou Hui Li Kai Wang Yanbin He Yan Chen Xiaoxiao Ni Yechun Guo Wei Lv Jiechun Zhang Qiuyou Xie Ronghao Yu | 2018 | Neuroscience Bulletin2018，34，4： | 3 |

| 5 | INTERFERENCE ESTIMATION AND ITS APPLICATIONS IN COGNITIVE RADIO NETWORKS显示文摘Cognitive Radio(CR) has been proposed as a system-level means to improve the spectrum utilization efficiency.The most significant premise for CR networks is to avoid harmful interference to the licensed users.Therefore,it is very important to estimate the potential inter-ference introduced by the deployment of CR networks so that CR networks can be coexistence with Licensed User(LU) networks by designing proper system parameters.In this paper,two statistical models of potential interference due to CR networks are developed based on transmitter and receiver oriented spectrum sensing schemes,respectively.The approximate probability dis-tributions of aggregate interference introduced by CR networks are then derived with respect to the obtained models.With the help of these probability distributions,a method is further pre-sented to get the critical system parameter,i.e.,sensing distance and user density of the CR networks,so that the introduced interference can be controlled to predefined level.Numerical results validate the proposed interference estimation method and confirm the effectiveness of in-terference distribution based system parameter design. | Chen Ronghao Chen Wei Wang Jun Li Shaoqian | 2010 | Journal of Electronics(China)2010，27，5： | 0 |
