Abstract

In this paper, the derivative of the instantaneous phase of electroencephalographic (EEG) signals is used as a basis for monitoring of global cerebral ischemia. Visual and quantitative results were obtained from six rodents that were subject to 3, 5 and 7 minutes of global ischemic brain injury by asphyxic cardiac arrest. Results show that the variations in the instantaneous phase are capable of amplifying the variations during the various stages of the recovery process and may serve as a novel analytical approach to grade and classify brain rhythms during global ischemic brain injury and recovery.

摘要

在本文中，脑电图（EEG）信号瞬时相位的导数被用作监测全脑缺血的基础。通过窒息性心脏骤停对六只啮齿动物造成3、5和7分钟的全脑缺血性脑损伤，获得了视觉和定量结果。结果表明，瞬时相位的变化能够放大恢复过程各个阶段的变化，并可作为一种新的分析方法，用于对全脑缺血性脑损伤和恢复过程中的脑节律进行分级和分类。
