摘要:
血流动力学响应函数(HRF)是神经活动和功能磁共振成像(fMRI)之间的数学传递函数,与神经血管生理相关,其中携带着很多与脑功能和脑疾病病理相关的信息,而这些信息是不能用传统的fMRI分析得到的。本研究主要对HRF的研究进展进行综述,对fMRI和HRF进行介绍分析,重点介绍HRF的3个参数,即响应高度、到达峰值时间和半高全宽,随后介绍了一种反卷积估计HRF参数的方法,并对近年来HRF与脑疾病病理相关的研究现状进行总结。HRF与强迫症、自闭症谱系障碍、创伤后应激障碍和脑损伤等脑疾病的病理相关,对HRF进行建模和参数提取可以得到更多潜在的神经病理信息。HRF分析可以作为脑疾病病理研究的窗口,为传统的fMRI分析提供新的研究视角和方法。
Abstract:
Abstract: Hemodynamic response function (HRF) which is a mathematical transfer function between neural activity and functional magnetic resonance imaging (fMRI) is related to neurovascular physiology and carries a lot of information related to brain function and pathology of brain diseases which cant be obtained by traditional fMRI analysis. Herein the advances in HRF are reviewed. A basic introduction to fMRI and HRF is given, mainly focusing on 3 parameters of HRF, namely response height, time-to-peak and full-width at half-max. Then, a deconvolution method to estimate HRF parameters is introduced, and the research status of HRF related to the pathology of brain diseases in recent years is summarized. It is found that HRF is associated with the pathology of brain diseases such as obsessive-compulsive disorder, autism spectrum disorder, post-traumatic stress disorder and brain injuries. Modeling and parameters extraction of HRF can provide more potential neuropathological information. HRF analysis can be used as a window for pathological study of brain diseases and provides a new perspective and method for traditional fMRI analysis.
