A deeper understanding of cortical sources can be provided by source imaging techniques. These methods first create mathematical models of the head, assigning appropriate properties to each layer. Brain activity is then calculated based on these assigned models and the observed EEG measurements, greatly...
这些研究表明,高密度头皮脑电图对癫痫病灶定位的精确度平均约为±15毫米。使用癫痫成功手术后的切除区域作为定位的基础研究表明,脑电源成像分析(EEG source imaging,ESI)成功地以大约85%的准确度识别了癫痫区域。其他研究将EEG或MEG源定位分析与颅内诱发电位、电皮层刺激或功能磁共振成像(fMRI)进行比较,也证明了使用这...
EEG source imaging Objective: Electroencephalography (EEG) is an important tool for studying the temporal dynamics of the human brain's large-scale neuronal circuits. However... CM Michel,MM Murray,G Lantz,... - 《Clinical Neurophysiology》 被引量: 2142发表: 2004年 EEG source imaging Objective...
EEG source imaging (ESI) is a model-based imaging technique that integrates temporal and spatial components of EEG to identify the generating source of electrical potentials recorded on the scalp. Recent advances in computer technologies have made the analysis of ESI data less time-consuming, and ...
现在的源定位(sourcelocalization)和源成像(sourceimaging)方法,可以把脑电信号定位到大脑皮层的特定位置上,分辨率最高能达到5毫米左右。5毫米的...实验室目前的研究重点。作为旁观者,我认为这是可能在5到10年内产生重要成果的方向。 在无创方面,脑电信号的分析方法一定还会提高。此外,我认为我们不能只做计算,实验...
The ill-posed nature of the MEG (or related EEG) source localization problem requires the incorporation of prior assumptions when choosing an appropriate solution out of an infinite set of candidates. Bayesian approaches are useful in this capacity because they allow these assumptions to be ...

To compare EEG source imaging results with the actual DBS electrode positions, identified from post-op computer tomography (CT), we spatially aligned imaging data from these different modalities (Fig. 1a, Supplementary Figure 1). Fig. 1 Electrode implantation and electrophysiological recordings in the...
Approximate Average Head Models for EEG Source Imaging We examine the performance of approximate models (AM) of the head in solving the EEG inverse problem. The AM are needed when the individual's MRI is not av... PA Valdés-Hernández,NV Ellenrieder,A Ojeda-Gonzalez,... 被引量: 0发表:...
