摘要

当大脑某一区域的神经活动增加时，由于血液氧合的变化，该区域产生的局部磁共振信号会少量增加。这种血氧水平依赖性(BOLD)效应是目前大多数功能性磁共振成像(fMRI)研究的基础，该研究旨在绘制人类工作大脑的激活模式。在本教程中，我们将回顾用于分析功能磁共振成像数据的主要技术。

FMRI: Principles and analysis

When neural activity increases in a region of the brain, the local magnetic resonance signal produced in that part of the brain increases by a small amount owing to changes in blood oxygenation. This blood oxygenation level dependent (BOLD) effect is the basis for most functional magnetic resonance imaging (fMRI) studies done today to map patterns of activation in the working human brain. In this tutorial we will review the main techniques used to analyze fMRI data.
