This study investigated the dynamic brain mechanisms of the visual spatial attention scale under different attention scales. 研究视觉空间注意中不同注意范围引起脑内加工时程的动态变化。
PET and fMRI because of the lower temporal resolution could not be accurately stated the processing time of dynamic brain processes, so, many studies have focused on its sub-components of brain function. 由于PET和fMRI的时间分辨率较低,无法精确阐明大脑动态加工的时间进程,所以,已有研究多侧重其子成分的脑功能定位。
The intelligent dynamic brain supervised of permanent pressure can realize nobody value guarding operating, raise the system work beneficial result, is easy to realize the industrial automation network control management, economizes two investments and save energy, so possesses extensively popularizes use value. 恒压智能动态监控控制系统能实现无人值守运行,提高系统工作效益,便于实现工业自动化网络控制管理,节省二次投资,又可节能,因此具有广泛推广使用价值。
Conclusion : ① The non-invasive dynamic brain edema monitor is sensitive and objective to reflect the change of cerebral edema in patients in craniotomy. 结论:(1)无创脑水肿动态监护仪可反映脑水肿动态变化。
On the basis of the property of different EEG rhythms, wavelet packet decomposition is used for designing filters with different frequency characteristics to detect the dynamic characteristics of different EEG rhythms, which are used to form the dynamic electrical brain activity mapping ( DBEAM ). 根据脑电信号的不同节律特性,提出应用小波包分解构造不同频率特性的滤波器,提取脑电信号不同节律的动态特性,并由此构造各种节律的动态脑(DB)电地形图。
