For almost three decades, functional magnetic resonance imaging (fMRI) has been one of the main tools in brain research. Yet a new study published in Nature Neuroscience fundamentally challenges the ...

A new study fundamentally challenges how fMRI data are interpreted, finding no valid coupling between oxygen content measured by MRI and neuronal activity.

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

A new study in Engineering introduces a novel MRI technique enabling real-time, artifact-free navigation of magnetic robots.

A new way of imaging the brain with magnetic resonance imaging (MRI) does not directly detect neural activity as originally reported, according to scientists at MIT's McGovern Institute. The method, ...

Septal circumferential strain (Ecc) was significantly decreased in LGE-negative boys with Duchenne muscular dystrophy (DMD) and correlated to ventricle changes. Researchers at the University of ...

In the original study, researchers led by Jang-Yeon Park of Sungkyunkwan University submitted anesthetized mice to whisker shocks while taking small segments of fMRI images milliseconds apart. This ...

Summary: Advanced imaging reveals that COVID-19 may cause lasting brain changes, even in people without ongoing symptoms, pointing to hidden neurological effects that could persist long after recovery ...

Magnetic resonance imaging (MRI) is a technique using magnets, radio waves, and a computer that produces images of soft tissues in the body, like muscles and organs. Unlike some other imaging tests, ...

Contradiction to the prevailing paradigm in neuroimaging  - No general relationship between oxygen content and neuronal activity - Conventional MRI method should be complemented by quantitative ...
