Neither focal spike-and-wave nor generalized spike-and-wave discharges had any effect on the EEG frequency or spectral power following the discharge. Conclusion: While interictal EEG discharges temporarily alter neural activity during the duration of the spike-and-wave discharge, there is no ...
他们用fNIRS-EEG系统测量HHb、O2Hb和HbT(左额区1个fNIRS通道,11个电极根据10-20系统定位)。他们记录了6例广泛棘慢波发放(generalized spike-and-wave discharges, GSWD)患者的额叶血流动力学波动。GSWD与额叶区组织氧合增加有关(在GSWD发生前10秒开始),随后是一个强的脱氧阶段,氧合和CBV再次增加,最后回到基线。W...

Transient. An isolated wave or pattern that is distinctly different from background activity. 1Spike: a transient with a pointed peak and a duration from 20 to under 70 msec. 2Sharp wave: a transient with a pointed peak and duration of 70-200 msec. ...
这些包括尖峰(spike)、锐波以及尖峰和波形放电(spike-and-wavedischarge)。特定脑部区域(诸如左侧颞叶)中的尖峰和锐波指示部分疾病发作可能来自于该区域。另一方面,大多数一般性癫痫由尖峰和波形放电所暗示,该尖峰和波形放电在脑部的两个半球上广泛分布,尤其在它们同时在两个半球中开始的情况下。

The EEG-signal was translated into a sequence of symbols coding information about fragments of records with EEG patterns detected as spike-wave forms. Their shape was described by only four parameters such as mobility of the form, spike variance, wave slope and sum of wave amplitudes. The ...
