Dissociating pain from its anticipation in the human brain

A Ploghaus, I Tracey, JS Gati, S Clare, RS Menon… - science, 1999 - science.org
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

…, SL Danckert, JFXD Souza, JS Gati, RS Menon… - Experimental brain …, 2003 - Springer
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

…, JS Gati, S Everling, RS Menon - Human brain …, 2013 - Wiley Online Library
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

…, JS Gati, S Clare, S Smith, RS Menon… - Journal of …, 2002 - Soc Neuroscience
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 …

Neural correlates of traumatic memories in posttraumatic stress disorder: a functional MRI investigation

…, RW Neufeld, JS Gati, RS Menon - American Journal of …, 2001 - Am Psychiatric Assoc
OBJECTIVE: The neuronal circuitry underlying posttraumatic stress disorder (PTSD) was
studied in traumatized subjects with and without PTSD. METHOD: Traumatized subjects with (N…

Brain activation during script-driven imagery induced dissociative responses in PTSD: a functional magnetic resonance imaging investigation

…, M Gupta, RWJ Neufeld, JS Gati, RS Menon - Biological …, 2002 - Elsevier
Background: The goal of this study was to examine the neuronal circuitry underlying
dissociative responses to traumatic script-driven imagery in sexual-abuse-related posttraumatic …

Experimental determination of the BOLD field strength dependence in vessels and tissue

JS Gati, RS Menon, K Uǧurbil… - Magnetic resonance in …, 1997 - Wiley Online Library
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 …

Motor area activity during mental rotation studied by time-resolved single-trial fMRI

…, R Summers, M Jarmasz, RS Menon… - Journal of Cognitive …, 2000 - direct.mit.edu
The functional equivalence of overt movements and dynamic imagery is of fundamental
importance in neuroscience. Here, we investigated the participation of the neocortical motor …

BOLD based functional MRI at 4 Tesla includes a capillary bed contribution: echo‐planar imaging correlates with previous optical imaging using intrinsic signals

RS Menon, S Ogawa, X Hu, JP Strupp… - Magnetic resonance …, 1995 - Wiley Online Library
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

…, BG Goodyear, JS Gati, RS Menon - Journal of …, 2001 - journals.physiology.org
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…
