Dissociating pain from its anticipation in the human brain
The experience of pain is subjectively different from the fear and anxiety caused by threats of
pain. Functional magnetic resonance imaging in healthy humans was applied to dissociate …

Visually guided grasping produces fMRI activation in dorsal but not ventral stream brain areas
Although both reaching and grasping require transporting the hand to the object location,
only grasping also requires processing of object shape, size and orientation to preshape the …

Resting‐state networks show dynamic functional connectivity in awake humans and anesthetized macaques
Characterization of large‐scale brain networks using blood‐oxygenation‐level‐dependent
functional magnetic resonance imaging is typically based on the assumption of network …

Imaging attentional modulation of pain in the periaqueductal gray in humans
Pain is an unpleasant sensory and emotional experience usually triggered by stimulation of
peripheral nerves and often associated with actual or potential tissue damage. It is well …

Experimental determination of the BOLD field strength dependence in vessels and tissue
High resolution functional MRI (fMRI) experiments were performed in human visual cortex at
0.5, 1.5, and 4 T to determine the blood oxygenation level dependent (BOLD) field strength …

BOLD based functional MRI at 4 Tesla includes a capillary bed contribution: echo‐planar imaging correlates with previous optical imaging using intrinsic signals
We show that the EPI time course in functional MR imaging at 4 Tesla displays a multiphasic
response in response to photic stimulation. Focal areas of gray matter display an initial …

Cerebral cortical representation of automatic and volitional swallowing in humans
Although the cerebral cortex has been implicated in the control of swallowing, the functional
organization of the human cortical swallowing representation has not been fully documented…
