In order to investigate the characteristics of sensorimotor cortex during motor execution(ME), voluntary, stimulated and imaginary finger flexions were performed by ten volunteer subjects. Electroencephalogram(EEG) data were recorded according to the modified 10-20 International EEG System. The patterns were compared by the analysis of the motion-evoked EEG signals focusing on the contralateral(C3) and ipsilateral(C4) channels for hemispheric differences. The EEG energy distributions at alpha(8—13 Hz), beta(14—30 Hz) and gamma(30—50 Hz) bands were computed by wavelet transform(WT) and compared by the analysis of variance(ANOVA). The timefrequency(TF) analysis indicated that there existed a contralateral dominance of alpha post-movement event-related synchronization(ERS) pattern during the voluntary task, and that the energy of alpha band increased in the ipsilateral area during the stimulated(median nerve of wrist) task. Besides, the contralateral alpha and beta event-related desynchronization(ERD) patterns were observed in both stimulated and imaginary tasks. Another significant difference was found in the mean power values of gamma band(p0.01)between the imaginary and other tasks. The results show that significant hemispheric differences such as alpha and beta band EEG energy distributions and TF changing phenomena(ERS/ERD) were found between C3 and C4 areas during all of the three patterns. The largest energy distribution was always at the alpha band for each task. 相似文献

阅读能力是教学思维的基础和前提,是教学能力的重要表现形式和核心.任何一门课程,部需要学生在阅读过程中汲取知识,在阅读过程中提升自己.对于数学的学习,无疑也要先从阅读书本开始.事实上,农村中学的学生数学阅谈能力偏低,他们大多只是机械地读文字,并没有在阅读中把握重点、知识点,更忽视了对文字内涵的理解. 相似文献

社会发展和农业现代化发展迫切需要高素质人才,当今中国农业女性成为生产的主力,由于传统文化、习俗影响,农村留守妇女整体文化素质相对较低,而教育又近似将这一群体边缘化,提升农村留守妇女综合素质迫在眉睫。 相似文献
