Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

Donepezil slows brain shrinkage in some patients with mild cognitive impairment

According to a new study, the drug donepezil measurably slows the rate of brain shrinkage in some patients with mild cognitive impairment, a pre-Alzheimer's disease condition. The shrinkage was measured by magnetic resonance imaging (MRI).

Researchers discover why brain areas fail to work together in autism

In people with autism, the brain areas that perform complex analysis appear less likely to work together during problem solving tasks than in people who do not have the disorder, report researchers working in a network funded by the National Institutes of Health.

Mild cognitive impairment: Evaluation with 4-T functional MR imaging

Memory loss associated with early Alzheimer's disease (AD) may be linked to altered activity in several areas of the brain, according to a study in the July issue of Radiology.

Broca's area and the hierarchical organization of human behavior

Researchers have discovered that Broca's area in the brain - best known as the region that evolved to manage speech production - is a major "executive" center in the brain for organizing hierarchies of behaviors.

That dreadful feeling - most choose more pain sooner rather than less later

According to research into why people experience the feeling of dread, a team of Emory neuroscientists led by Gregory Berns, MD, PhD, used functional magnetic resonance imaging (fMRI) to determine the areas of the brain that are activated when someone gets that dreadful feeling.

fMRI used to show dread responses in brain

In order to better understand how people make decisions when the outcomes are known to be unpleasant, a team of Emory neuroscientists led by Gregory Berns, MD, PhD, used functional magnetic resonance imaging (fMRI) to determine the areas of the brain that are activated when someone experiences dread.
