Despite the long-standing reputation of each, as well as distinct underlying physics, laser speckle contrast imaging (LSCI) ...

Investigators used MRI to evaluate brain perfusion in patients with transfusion-dependent (n=54) and non–transfusion-dependent (n=23) β-thalassemia versus 56 controls. They found that relative ...

Fig. 1. CBF and Tmax maps derived from the model and CTP showing three patients with different cores and low perfusion volumes in the test dataset and the corresponding maximum intensity projection ...

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 ...

The Center for Neuroscience Imaging Research (CNIR) in the Institute of Basic Science (IBS), Suwon, Korea, is developing new neuroimaging approaches to explore biophysics, physiology, and biology, and ...

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

Laser speckle contrast imaging (LSCI) and imaging photoplethysmography (IPPG) are two simple, contact-free, camera-based ways to analyse cerebral ...

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 ...

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