Research output: Chapter in Book/Report/Conference proceeding › Chapter › peer-review

Abstract

The introduction to functional Magnetic Resonance Imaging (fMRI) article provides a description of the fMRI measurement and its neurobiological meaning. It starts by describing the principle of the MRI scanner focusing on the parts that are relevant to fMRI data. fMRI data measures changes of oxygen concentration in the blood, utilizing the Blood Oxygen Level Dependent Contrast. The article then describes current understanding of neurovascular coupling, the way in which the fMRI signal is linked to neural activity.
