Question

Quizplus · Accepted Answer

The signal derived in fMRI is based on changes in blood flow related to neural activity, which is a reflection of the metabolic activity of neurons. This technique measures the blood-oxygen-level dependent (BOLD) contrast, which is linked to neuronal metabolism, not directly to electrical activity, neurotransmitters, or the structural aspects of neurons like their age or the proportion of gray to white matter.
