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 ...

Explore how functional MRI reveals brain activity by measuring BOLD response, a key indicator of internal processing and neural firing. The more the brain cells are firing, the more oxygen they use up ...

Functional imaging is a fast-growing area of neuroscience, but suffers from an image problem: no-one is quite sure how the signals obtained using BOLD fMRI (blood-oxygen-level-dependent functional ...

“What we do know, of course, is what MRI measures,” said Robert Turner, director emeritus of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany. MRI measures the ...

Low-resolution images (LR) are input, and feature maps are obtained through 3×3 convolution. After passing through a residual in residual (RIR) module, followed by upsampling and a 3×3 convolution ...

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 ...

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 ...

Functional magnetic resonance imaging (fMRI) has the enormous potential to pinpoint neuronal damage in almost any part of the brain and could play an important part in the fight against Alzheimer ...

A quick flash of light has confirmed the key assumption justifying the use of functional magnetic resonance imaging to reveal the inner workings of living brains. In a study appearing online May 16 in ...

It all started with a rejected grant proposal. Ahmad Hariri, a neuroscientist at Duke University, was interested in using so-called “task fMRI”—in which subjects perform specially designed cognitive ...
