Reduced Brainstem Inhibition during Anticipated Pelvic Visceral Pain Correlates with Enhanced Brain Response to the Visceral Stimulus in Women with Irritable Bowel Syndrome

Deficits in preparatory inhibition of DBS may interfere with descending corticolimbic inhibition and contribute to enhanced brain responsiveness and perceptual sensitivity to visceral stimuli in IBS.

Abnormal endogenous pain modulation and somatic and visceral hypersensitivity in female patients with irritable bowel syndrome.

A majority of IBS patients had abnormal endogenous pain modulation and somatic hypersensitivity as evidence of central sensitization.

Mapping of Brain Activations to Rectal Balloon Distension Stimuli in Male Patients with Irritable Bowel Syndrome Using Functional Magnetic Resonance Imaging

Differential activation among patients with IBS-C and IBS -D was seen in the brain regions controlling affective motivation, homeostatic emotions, and autonomic responses to pain.

Visceral pain perception in patients with irritable bowel syndrome and healthy volunteers is affected by the MRI scanner environment

The scanner environment significantly increased visceral, but not somatic, pain perception in irritable bowel syndrome patients and healthy controls in a protocol specifically aimed at investigating visceral pain.

Quantitative meta-analysis identifies brain regions activated during rectal distension in irritable bowel syndrome.

The results support a role for central nervous system dysregulation in IBS and provide specific targets for guiding development of future neuroimaging protocols to more clearly define altered brain-gut interactions in Ibs.

Electrophysiological investigation of the contribution of attention to altered pain inhibition processes in patients with irritable bowel syndrome

The results of this study indicate that the central pain inhibition deficit in IBS reflects interactions between several brain processes related to pain and attention.

The balancing act: endogenous modulation of pain in functional gastrointestinal disorders

Brain imaging during specific activation of endogenous pain modulation demonstrates a fairly consistent functional hub of mainly frontal, limbic and brainstem modulatory regions in healthy humans, which may well be a unifying pathophysiological mechanism in FGID.



Brain functional magnetic resonance imaging of rectal pain and activation of endogenous inhibitory mechanisms in irritable bowel syndrome patient subgroups and healthy controls

IBS-C and IBS-D appear to have differing abnormal endogenous pain inhibitory mechanisms, involving DNIC and other supraspinal modulatory pathways.

Central processing of rectal pain in patients with irritable bowel syndrome: an fMRI study

This study reveals aberrant functional responses to noxious rectal stimulation in patients with irritable bowel syndrome, adding grounds to the hypothesis that the central nervous system plays a significant role in the pathophysiology of this syndrome.

Alteration of the spinal modulation of nociceptive processing in patients with irritable bowel syndrome

The results provide direct evidence that a hyperexcitability of spinal nociceptive processes is present in a large subgroup of IBS patients, and the RIII reflex was significantly facilitated during slow ramp distension and inhibitions induced by rapid distensions were significantly reduced.

Abnormal forebrain activity in functional bowel disorder patients with chronic pain

Percept-related fMRI revealed abnormal urge- and pain-related forebrain activity during rectal distension in patients with irritable bowel syndrome (IBS), revealing the sensory symptoms of rectal pain and hypersensitivity, visceromotor dysfunction, and abnormal interoceptive processing.

Visceral Afferent Pathways and Functional Brain Imaging

A brief introduction to the development of brain science as it relates to pain processing and a snapshot of recent functional imaging results with somatic and visceral pain is provided.

Keeping pain out of mind: the role of the dorsolateral prefrontal cortex in pain modulation.

It is proposed that the DLPFC exerts active control on pain perception by modulating corticosubcortical and corticocortical pathways.

Comparisons of pain and vibrotactile stimulation revealed that both stimuli produced activation in similar regions of SI and SII, regions long thought to be involved in basic somatosensory processing, which reflects the complex nature of pain.
