Fluorescence recording of neural activity in the magnetic resonance scanner is a new strategy for examining the cellular underpinnings of blood oxygenation level–dependent (BOLD) functional magnetic ...

MRI signals don’t always match the brain’s true activity levels, overturning a core assumption used in tens of thousands of studies.

Four-element array coils and high field small animal MR scanners can be used to obtain functional MRI, also known as fMRI, at a high spatial resolution of 75 x 75 x 1000 μm 3. The activation area ...

BOLD contrast fMRI is a useful alternative to overcome this limitation. In this method, a contrast agent is injected in blood to quantitatively detect blood flow at baseline. BOLD contrast is resulted ...
