When the brain is stimulated, blood flow increases. For 30 years, functional magnetic resonance imaging (fMRI), one of the ...

Chronic pain affects nearly one in five adults worldwide and remains one of the leading causes of disability. Unlike acute pain triggered by injury, chronic pain often arises spontaneously—without an ...

Researchers found found that as people's arousal levels dwindle during an fMRI, such as if they become more relaxed and sleepy, resulting changes in breathing and heart rates alter blood oxygen levels ...

This section is focused on in vivo studies of human beings and animals in health and disease enabled by very-high-field magnetic resonance imaging and spectroscopy. Much of the material presented here ...

A new approach to fMRI scanning offers a three-dimensional look at brain activation. fMRI is already a 3D technique, of course, but in the case of the cerebral cortex - which is what the great ...

Much like camera settings—filters, flashes and focus—affect what we notice in a final photo, the way scientists measure something can affect how we interpret and understand it. This is especially true ...

Researchers have joined forces to give a boost to spatial memory by creating a unique experimental setup that combines non-invasive deep-brain stimulation, virtual reality training, and fMRI imaging.

Novel, noninvasive testing is able to predict dementia onset with 80% accuracy up to 9 years before clinical diagnosis. The results suggest resting-state functional MRI (rs-fMRI) could be used to ...

Upper panel displays functional MRI (fMRI) maps obtained from the functional connectivity multivariate patterns analysis conducted on dataset 1 and dataset 2. In particular, the average connectivity ...
