scans use magnetic fields and radio waves to measure subtle changes in blood flow to detect which brain cells and circuits are active or inactive.
Total quantity or scope: EEG with 128 channel performance analysis of spontaneous activity during functional MRI
examination - 1 piece
can only identify which brain regions are affected by pain.
Whelan and his colleagues analyzed their data using a factor analysis approach instead of the mass univariate approach commonly used in functional MRI
In current practice, structural MRI is used primarily to survey the brain for gross abnormalities such as lesions, atrophy, or stroke, while clinical use of functional MRI
is restricted mostly to presurgical brain mapping.
A mainstay of many neuroscience labs, functional MRI
relies on blood flow changes in the brain to serve as proxies for nerve cell activity.
Participants in this study were asked to choose the most logical of three possible endings as they watched a series of comic strip vignettes while a functional MRI
scanner measured brain activity.
PARIS - Transcranial magnetic stimulation guided by functional MRI
reduced auditory hallucinations in patients with schizophrenia, but so did a sham treatment in a randomized, controlled study of 62 patients.
The study, done with functional MRI
, showed that the same area of the brain was pleasurably stimulated by the two activities.
CHICAGO -- Functional MRI
imaging has shown that patients with Alzheimer's disease need to use more of their brains to successfully solve a working memory task, compared with control subjects, Dr.
The Symphony Power-class features a wide range of capabilities, from routine applications to high-end applications such as functional MRI
Recent studies have revealed new insights about its organization by the combination of structural Magnetic Resonance Imaging (MRI) such as tractography (using Diffusion Spectrum Imaging, DSI) and functional MRI
(fMRI) using resting-state.
This quick dip in blood volume, a phenomenon that's also seen in functional MRI
, may represent the brain preparing for work by shunting waste-ridden blood out via the jugular vein.
They tested healthy young drivers operating a novel driving simulator equipped with a steering wheel, brake pedal and accelerator inside a high-powered functional MRI
Topics addressing normal-appearing gray matter include assessing its pathology, measuring imaging gray matter volume, assessing magnetization transfer and diffusion-weighted imaging, and using MR spectroscopy and functional MRI
