查询词典 EEG

The main peaks of the EEG power spectra were in delta and theta frequency range. In the stage of ethanol exposure, the rats exhibited much more act of attack than the control, the alpha waves of EEG decreased, while the delta waves increased. The EEG power spectra analysis showed the delta power increased and the theta power decreased. In the stage of ethanol withdrawal, the rats showed some withdrawal behaviors such as wet dog shakes, sniffing, groomingand tonic-clonic seizures for audiogenic stimulus. Spikes and spike-slow waves were found in the EEG. In power spectra analysis, the delta power decreased while the alpha and the theta power increased, the EEG frequency band moved to the high-frequency rang. These changes were found obviously on the sixth day and disappeared on the 1 Oth day after the ethanol was removed.

本研究发现：1、对照组大鼠行为无异常，伏核EEG以α节律为主，散在出现δ和θ节律；功率主峰在δ和θ频段范围，整个过程中未发现手术对伏核EEG及脑电功率谱有影响。2、在慢性饮酒过程中，大鼠攻击性行为增加，伏核 EEG的α节律明显减少，散在出现的高幅慢活动δ波逐渐增多，功率谱分析表明δ频段功率百分比明显增加，而θ频段功率百分比明显减少，总功率减少。3、停饮后，大鼠出现湿狗样抖动、打喷嚏等撤药综合症，并且高频声音刺激能引发惊厥；伏核EEG出现棘波和棘慢综合波，并持续增多，功率谱分析显示δ频段功率百分比 5 南京医科大学硕士学位论文逐渐减少，而0和以频段功率百分比逐渐增加，总功率增加。

In order to improve the classification accuracy of mental EEG, the rhythm assimilation effect of EEG was used in the study of mental task classification firstly in this dissertation. A series of experiments schemes, which try to make different types of mental EEG carried with different and classifiable rhythm assimilation information, were projected and the rhythm assimilation phenomenon of different type mental EEG was explored detailedly.

Here are three core contents of such framework:(1) cognitive process is reflected by the temporal, frequency, and spatial evolutions of EEG signals;(2) cognitive process is reflected by different nonlinear oscillations and transients of EEG signals;(3) cognitive process is reflected by the linear/nonlinear coupling and synchronization of EEG signals at different brain regions.

本文的一个理论创新在于首次提出认知动力学系统这一新概念，使得对认知功能的研究建立在一个理论框架下，其核心内容包括三方面：(1)认知过程通过EEG脑电活动在时间，频率，空间上的动态演化体现出来；(2)认知过程通过EEG脑电活动的非线性振动与各种刺激诱发的暂态体现出来；(3)认知过程通过EEG脑电活动在各脑区的相互耦合与同步谐振体现出来。

Sleep-deprivation EEG was performed individually. Results The sleep deprivation EEG showed slow background electric activity in all 3 groups. In addition, the rates of EEG abnormality for nonepileptic seizures group were zero, no statistics were computed because F was a constant. Fifty-seven cases showed spindle/sharp-slow wave complex in suspected epileptic children.

结果 所有病例脑电图的背景电活动频率均明显变慢，非癫癎发作组38例睡眠EEG诱发试验均为阴性，因其诱发试验前后数据一致，故该组无统计意义；拟诊癫癎组脑电图有棘／尖慢复合波等癫癎样放电者57例(559%)；对照组诱发后脑电图异常出现2例(1.9%)癫癎样放电者，3组比较有非常显著差异(x^2=97.3 P0.01)。

ResultsIdiopathic nocturnal frontal lobe epilepsy has distinctive clinical seizure characteristics. The onset age is younger than 20 and the ratio of male cases to female cases is 2 to 1. The most notable clinical characteristics are nocturnal clustered postural or dystonic seizures and complex motor activities, with 14% of the patients have epileptic family history. The interictal routine EEG of 22.9% and active EEG of 28% cases in wakeness and 38% cases in sleep showed frontal lobe epileptiform discharge while the ictal EEG of 66.7% cases showed frontal lobe epileptiform discharge. Drug therapy is effective in 80% cases with 30% completely controlled.
