NIRS LFOs trace alternant TA-burst Low frequency

项目摘要

Low frequency oscillations (LFOs), which are defined as frequencies between 0.01-0.1 Hz, have increasingly recognized using monitoring cerebral blood flow, metabolism and function. Previous report ,which investigated NIRS and EEG in preterm infants, found pronouncing coherence between LFOs and burst activities during the trace alternant EEG phase. They concluded that NIRS-LFOs might be the consequence of BOLD phenomenon induced by oxygen consumption during burst activities. The aim of this study was to investigate the relationship between electro-cortical activities and NIRS-LFOs during every sleep stages in healthy neonates. We measured 13 records. The results were as below, we confirmed the correlation between electro-cortical activities and NIRS-LFOs, the power of NIRS-LFOs was observed every sleep stages. Because NIRS-LFOs occurred without electro-cortical activities, it suggested the existence of the origin of electro-cortical activities and LFOs in oxygen availability.

低频振荡（LFOs）被定义为频率在0.01-0.1 Hz之间，越来越多地被用于监测脑血流、代谢和功能。先前的报道调查了早产儿的近红外光谱和脑电图，发现在微量交替脑电图阶段，LFOs和爆发活动之间存在明显的一致性。他们得出结论，nirs - lfo可能是爆发活动中氧气消耗引起的BOLD现象的结果。本研究旨在探讨健康新生儿各睡眠阶段脑电皮层活动与NIRS-LFOs之间的关系。我们测量了13条记录。结果如下，我们证实了电皮层活动与NIRS-LFOs之间的相关性，并在每个睡眠阶段观察NIRS-LFOs的功率。由于NIRS-LFOs发生时没有电皮层活动，提示电皮层活动和LFOs的起源与氧有效性有关。
