An MRI time course of 512 echo‐planar images (EPI) in resting human brain obtained every
250 ms reveals fluctuations in signal intensity in each pixel that have a physiologic origin. …

BACKGROUND AND PURPOSE: In subjects performing no specific cognitive task (“resting
state”), time courses of voxels within functionally connected regions of the brain have high …

BACKGROUND AND PURPOSE: In subjects who are performing no prescribed cognitive task,
functional connectivity mapped with MR imaging (fcMRI) shows regions with synchronous …

We performed functional MRI (FMRI) in 22 consecutive epilepsy patients undergoing intracarotid
amobarbital (Wada) testing and compared language lateralization measures obtained …

BACKGROUND AND PURPOSE: Disruption of the cytoskeletal network and axonal membranes
characterizes diffuse axonal injury (DAI) in the first few hours after traumatic brain injury. …

Study Design. A biomechanical and imaging study of human cadaveric spinal motion
segments. Objective. To investigate the effect of both disc degeneration and facet joint …

Previous research has suggested that cerebral lesions observed on magnetic resonance
imaging (MRI) of MS patients are clinically “silent.” We examined the validity of this assertion by …

Study Design A cadaveric study was done to analyze the dimensional changes in the spinal
canal and intervertebral foramen of the lumbar spine with flexion and extension movements. …

One hundred lumbar intervertebral foramina from eighteen spines of fresh cadavera were
studied to assess the relationship between compression of the nerve root and the height of the …

Background context: A relationship between degenerative changes of the intervertebral disc
and biomechanical functions of the lumbar spine has been suggested. However, the exact …
