Functional neuroimaging (FNI) techniques, such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), gain access to the activity of the brain through changes in blood flow and metabolism that accompany, with remarkable fidelity, regional changes in the activity of the brain. While the temporal resolution of these techniques falls far below that of the electrophysiological techniques, they do offer full 3D coverage of the human brain at subcentimeter resolution. This chapter focuses on fMRI BOLD imaging, which is now the dominant FNI technique.
