我们引入了一种自下而上的模型，用于将脑电图（EEG）或脑磁图（MEG）与功能磁共振成像（fMRI）相结合。基于皮质微柱及其连接的生理原理，提出了扩展的神经质量模型。通过引入刺激和神经活动之间的关系，并使用所得的神经活动作为扩展 Balloon 模型的输入，从所提出的神经质量模型中提取 fMRI 信号。所提出的模型经过模拟验证，有助于评估即将推出的同步分析 MEG/EEG 和 fMRI 的组合方法。
We introduce a bottom-up model for integrating electroencephalography (EEG) or magnetoencephalography (MEG) with functional magnetic resonance imaging (fMRI). An extended neural mass model is proposed based on the physiological principles of cortical minicolumns and their connections. The fMRI signal is extracted from the proposed neural mass-model by introducing a relationship between the stimulus and the neural activity and, using the resultant neural activity as input of the extended Balloon model. The proposed model, validated using simulations, is instrumental in evaluating the upcoming combined methods for simultaneous analysis of MEG/EEG and fMRI.
