本文介绍了一种脑电图-fmri 多模态成像方法, 称为时空 fmri 约束脑电图源成像方法。所提出的方法采用有条件的功能磁共振成像子图, 或先验, 以提高空间特异性和限制错误结果的方式引导脑电图源定位。

这种方法可以帮助回答神经科学领域的关键问题,例如确定多个大脑区域之间的时间关系或探索复杂认知过程的详细神经通路。该技术的主要优点是它允许以空间和时间特定的方式整合多模态 EEG 和功能数据,以提高功能神经成像的分辨率和准确性。这项技术的影响延伸到对癫痫和神经认知障碍的理解。

因为该方法提高了无创神经成像的空间和时间准确性。虽然这种方法可用于提供对视觉运动和情绪处理系统的洞察力,但它也可以应用于其他系统,例如感觉运动整合、语言和记忆处理。这种方法的视觉演示至关重要,因为并发的 EEG 和 fMRI 数据记录步骤可能难以学习。
