The complex experience of pain is subserved by an extended network of brain areas. Recent evidence shows that painful stimuli modulate neuronal oscillations and synchrony in parts of the cerebral pain network. However, a comprehensive spatial and temporal characterization of pain-related neuronal oscillations and synchrony has not yet been carried out. Moreover, the functional significance of these pain-related phenomena has remained largely unknown. We will therefore use electroencephalography to investigate pain-induced oscillations and synchrony in the human brain. In a series of four experiments, we will apply advanced analysis techniques to spatially and temporally determine pain-induced neuronal oscillations in different frequency bands. Furthermore, we will explore synchrony between local oscillations as a measure of pain-related communication between brain areas. Pain-induced oscillations and synchrony will be related to spontaneous neuronal oscillations and to the well-known pain-evoked responses. Different perceptual and motor paradigms will be applied to investigate the functional significance of pain-induced oscillations and synchrony for the perception of and behavioral reactions to pain. The project is thus intended to provide a spatial, temporal and functional synopsis of neurophysiological phenomena in the human brain related to the complex experience of pain.

大脑区域的扩展网络促进了复杂的疼痛体验。最近的证据表明，疼痛刺激调节部分大脑疼痛网络的神经元振荡和同步。然而，尚未对疼痛相关的神经元振荡和同步性进行全面的空间和时间表征。此外，这些与疼痛相关的现象的功能意义在很大程度上仍然未知。因此，我们将使用脑电图来研究人脑中疼痛引起的振荡和同步性。在一系列的四个实验中，我们将应用先进的分析技术在空间和时间上确定不同频带中疼痛引起的神经元振荡。此外，我们将探索局部振荡之间的同步性，作为大脑区域之间与疼痛相关的沟通的衡量标准。疼痛引起的振荡和同步性与自发神经元振荡和众所周知的疼痛诱发反应有关。将应用不同的感知和运动范式来研究疼痛引起的振荡和同步性对疼痛感知和行为反应的功能意义。因此，该项目旨在提供人脑中与复杂的疼痛体验相关的神经生理学现象的空间、时间和功能概要。
