Over the last few years, researchers have used a type of brain scanning, known as functional magnetic resonance imaging fMRI, to help them map changes in blood flow in the brain and to correlate this with thoughts and behavior. A new way to analyze fMRI data, which could improve is reported in the International Journal of Computational Biology and Drug Design. Scientists have known since the 1890s that changes in blood flow and blood oxygenation in the brain (hemodynamics) are correlated with...

By Dan Vergano Images that purport to show -- in living color -- the parts of the brain that generate such virtues as compassion, fairness and wisdom are invading turf that was once reserved for philosophers, theologians and psychologists. From morality to math, a revolution in "functional" magnetic resonance imaging (fMRI), which observes brain blood flow, is being used by researchers to pinpoint the pieces of the brain that people rely on to think and feel. So, what's the problem?...

Although Alzheimer's disease affects millions of people worldwide, there is no way to identify this devastating brain disease at its earliest stages when there still may be time to delay or even prevent the downward spiral into dementia. In research settings, scientists are using sophisticated tools like MRI and PET to distinguish characteristics of brain function and anatomy that indicate future problems, providing a sort of screening test for the brain. Now a new study by a research group...

OAK BROOK, Ill. - Functional magnetic resonance imaging (fMRI) of the brain reduces the need for invasive testing of seizure disorder patients being considered for surgical treatment, according to a study published in the July issue of the journal Radiology. "fMRI gives the surgical team an important roadmap of the brain function without contrast injections or invasive tests," said the study's lead author, L. Santiago Medina, M.D., M.P.H., co-director of neuroradiology and director of the...
