Spontaneous and stimulus-induced oscillatory EEG activities range over a wide scope of frequencies from 1 Hz to 1 kHz. In the ultrafast domain, trains of 5-10 micropotentials are superimposed to primary thalamic and cortical components in somtosensory evoked potentials (SEP) as brief bursts of 1000 Hz and 600 Hz, respectively. Over the last years, hypotheses on generators and functions of this frequency-edge of population activity have been elaborated in numerous studies. Here, the relevant findings and ideas were surveyed from the body of literature. Special emphasis was paid to the anatomical and cellular origin of burst SEP, their assumed impact on somatosensory coding and perspectives for scientific as well as clinical applications.
自发的和刺激诱发的振荡性脑电图活动涵盖从1赫兹到1千赫兹的广泛频率范围。在超快领域，5 - 10个微电位序列分别作为1000赫兹和600赫兹的短暂爆发叠加到体感诱发电位（SEP）中的初级丘脑和皮层成分上。在过去几年中，众多研究阐述了关于这种群体活动频率边缘的发生器和功能的假说。在此，从文献中对相关发现和观点进行了综述。特别强调了爆发性SEP的解剖学和细胞起源、它们对体感编码的假定影响以及科学和临床应用的前景。
