Dynamic magnetic resonance imaging of human brain activity during primary sensory stimulation.
Neuronal activity causes local changes in cerebral blood flow, blood volume, and blood oxygenation. Magnetic resonance imaging (MRI) techniques sensitive to changes in cerebral blood flow and bloodExpand

Borders of multiple visual areas in humans revealed by functional magnetic resonance imaging.
The borders of human visual areas V1, V2, VP, V3, and V4 were precisely and noninvasively determined. Functional magnetic resonance images were recorded during phase-encoded retinal stimulation. ThisExpand

High angular resolution diffusion imaging reveals intravoxel white matter fiber heterogeneity
Magnetic resonance (MR) diffusion tensor imaging (DTI) can resolve the white matter fiber orientation within a voxel provided that the fibers are strongly aligned. However, a given voxel may containExpand

Functional analysis of human MT and related visual cortical areas using magnetic resonance imaging
Using noninvasive functional magnetic resonance imaging (fMRI) technique, we analyzed the responses in human area MT with regard to visual motion, color, and luminance contrast sensitivity, andExpand

Dynamic Statistical Parametric Mapping Combining fMRI and MEG for High-Resolution Imaging of Cortical Activity
Functional magnetic resonance imaging (fMRI) can provide maps of brain activation with millimeter spatial resolution but is limited in its temporal resolution to the order of seconds. Here, weExpand

Changes in cortical activity during mental rotation. A mapping study using functional MRI.
Mental imagery is an important cognitive method for problem solving, and the mental rotation of complex objects, as originally described by Shepard and Metzler (1971), is among the best studiedExpand

Functional mapping of the human visual cortex by magnetic resonance imaging.
Knowledge of regional cerebral hemodynamics has widespread application for both physiological research and clinical assessment because of the well-established interrelation between physiologicalExpand

Functional neuroanatomy of biological motion perception in humans
We used whole brain functional MRI to investigate the neural network specifically engaged in the recognition of “biological motion” defined by point-lights attached to the major joints and head of aExpand

Assessing and improving the spatial accuracy in MEG source localization by depth-weighted minimum-norm estimates
Cerebral currents responsible for the extra-cranially recorded magnetoencephalography (MEG) data can be estimated by applying a suitable source model. A popular choice is the distributed minimum-normExpand

Perfusion imaging with NMR contrast agents
Knowledge of regional hemodynamics has widespread application for both physiological research and clinical assessment. Here we review the use of MR contrast agents to measure tissue perfusion. TwoExpand
