Accurate description of human brain function requires the separation of true neural signal from noise. Recent work examining spatial and temporal properties of whole-brain fMRI signals demonstrates how artifacts from a variety of sources can persist after rigorous processing, and highlights the lack of consensus on how to address this challenge.
对人类大脑功能的准确描述需要从噪声中分离出真正的神经信号。最近一项研究全脑功能磁共振成像(fMRI)信号时空特性的工作表明,经过严格处理后,来自各种来源的伪影是如何持续存在的,并突出了在如何应对这一挑战方面缺乏共识的问题。
