Abstract:
Brain activity may manifest itself as oscillations which are repetitive rhythms of neuronal firing. These local field potentials can be measured via intracranial electroencephalography (iEEG). This review focuses on iEEG used to map human brain structures involved in olfaction. After presenting the methodology of the review, a summary of the brain structures involved in olfaction is given, followed by a review of the literature on human olfactory oscillations in different contexts. A single case is provided as an illustration of the olfactory oscillations. Overall, the timing and sequence of oscillations found in the different structures of the olfactory system seem to play an important role for olfactory perception.
摘要:
大脑活动可能表现为振荡,这是神经元放电的重复节律。这些局部场电位可以通过颅内脑电图(iEEG)测量。这篇综述的重点是用于绘制嗅觉相关人脑结构的iEEG。在介绍了审查的方法之后,总结了嗅觉涉及的大脑结构,其次是对不同背景下人类嗅觉振荡的文献进行回顾。提供了一种情况作为嗅觉振荡的说明。总的来说,在嗅觉系统的不同结构中发现的振荡的时间和顺序似乎对嗅觉感知起着重要作用。
