Zusammenfassung
Functional magnetic resonance imaging (fMRI) and other non-invasive imaging methods have greatly expanded our knowledge of human brain function. Although MRI was invented in the early 1970s and has been used clinically since the mid-1980s, its use in cognitive neuroscience expanded greatly with the advent of blood oxygenation level dependent (BOLD) functional imaging, and by now, fMRI is a mainstay of neuroscience research. This chapter gives an overview of the relation between the BOLD signal and the underlying neural signals. It focuses on intracortically recorded neural signals, recorded with microelectrodes.
