What Does BOLD Stand For?

BOLD stands for Blood Oxygenation Level Dependent

BOLD, which stands for Blood Oxygenation Level Dependent, refers to a functional imaging technique often used in neuroimaging and other medical diagnostics. It measures changes in blood flow and oxygenation levels in the brain and tissues, providing insights into neural activity and metabolic processes. This approach is fundamental in techniques like functional magnetic resonance imaging (fMRI), where it helps researchers and clinicians understand brain function and identify areas involved in different cognitive tasks.
