Researchers report that they have developed a method to combine three brain-imaging techniques to more precisely capture the timing and location of brain responses to a stimulus. Their study is the first to combine the three widely used technologies for simultaneous imaging of brain activity. The work is reported in the journal Human Brain Mapping. The new "trimodal" approach combines…

In a new study, led by the University of Glasgow, scientists show that brain activity recorded using functional magnetic resonance imaging (fMRI) may help predict response to CBT in depression before the treatment commences. The advances could help patients receive the most appropriate treatment for depression in a timely manner.
Scientists have identified mechanisms in the human brain that could help explain the phenomenon of the 'Uncanny Valley' - the unsettling feeling we get from robots and virtual agents that are too human-like. They have also shown that some people respond more adversely to human-like agents than others.
The speed of the human brain is remarkable. Almost immediately upon being exposed to stimuli, neurons are activated, prompting subconscious reactions and, a fraction of a second later, thought. But the speed at which we can noninvasively follow brain function using an MRI is not as impressive. Functional MRI (fMRI), which measures changes in blood-oxygen levels, has revolutionized neuroscience by…
Where are we coming from? Where are we going? Where are we right now? Our sense of spatial orientation gives us answers to these questions. We spoke with Professor Thomas Wolbers about the problems of diagnosing orientation disturbances and how the measurement of our sense of space could help in the fight against neuro-degenerative illnesses such as Alzheimer’s.
When light streams through her window in just the right way, Milena Canning will sometimes stoop to pick up a shiny coin she has noticed on the wooden floor of her Glasgow-area home. But her hand comes up empty – the 'coin' is just a dancing sunbeam, a quirk of perception in Canning's extraordinary world.
University of California, Irvine-led researchers, however, have found that high-resolution functional magnetic resonance imaging of the brain can be used to show some of the underlying causes of differences in memory proficiency between older and younger adults. The study involved 20 young adults (ages 18 to 31) and 20 cognitively healthy older adults (ages 64 to 89). In the study, the…
New information on dementia biomarkers is emerging, as increasing results from population studies become available. However, although the list of risk factors lengthens, the value of these predictors, and more generally the cause of disease, remain to be determined, according to Gabriel Krestin, professor and chairman of the Department of Radiology & Nuclear Medicine at Erasmus MC, University…

Integrated PET/MRI systems will permit the simultaneous acquisition of molecular, functional and structural parameters. The combined strengths of PET (high sensitivity and specificity, but relatively low spatial resolution) and MRI (high resolution, but low sensitivity) is the most attractive feature of multimodal imaging with hybrid scanners. Their application could substantially contribute to…

The Uliazpi Foundation in Spain, which studies and cares for severely mentally retarded patients, carried out an interesting study to identify bone mineral density values in a group of its patients, compare these with the general population and investigate the possible influence on these values on certain clinical variables and therapeutic regimens.
British researchers detected near-normal brain activity in patients who are believed to be in a persistent vegetative state (PVS) by using functional MRI. The findings may help doctors' to diagnose patients that might have a chance for recovery, but the researchers warn to over-intertpret their resulsts.
Functional MRI (fMRI) is a widely used method capable of mapping functional regions of the human cortex in near real time during specific tasks.
Despite advances in magnetic resonance imaging (MRI) that have revolutionised diagnostic possibilities, e.g. for functional imaging (fMRI), motion artifacts are still extremely detrimental in multi-slice 3D sequences, often used in fMRI or with uncooperative patients (children, elderly, accidents, stroke...).
