&NA; Visceral pain processing is abnormal in a majority of irritable bowel syndrome (IBS) patients. Aberrant endogenous nociceptive modulation and anticipation are possible underlying mechanisms investigated in the current study. Twelve IBS patients and 12 matched healthy controls underwent brain fMRI scanning during the following randomised stimuli: sham and painful rectal distensions by barostat without and with simultaneous activation of endogenous descending nociceptive inhibition using ice… Expand

Reduced Brainstem Inhibition during Anticipated Pelvic Visceral Pain Correlates with Enhanced Brain Response to the Visceral Stimulus in Women with Irritable Bowel Syndrome
TLDR
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. Expand
Abnormal endogenous pain modulation and somatic and visceral hypersensitivity in female patients with irritable bowel syndrome.
TLDR
A majority of IBS patients had abnormal endogenous pain modulation and somatic hypersensitivity as evidence of central sensitization. Expand
Mapping of Brain Activations to Rectal Balloon Distension Stimuli in Male Patients with Irritable Bowel Syndrome Using Functional Magnetic Resonance Imaging
TLDR
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. Expand
Decreased pain inhibition in irritable bowel syndrome depends on altered descending modulation and higher-order brain processes
TLDR
It is demonstrated that pain inhibition deficits in female IBS-D patients depend on two potentially separable mechanisms reflecting: (1) altered descending modulation and (2) higher-order brain processes underlying regulation of pain and affect. Expand
Visceral pain perception in patients with irritable bowel syndrome and healthy volunteers is affected by the MRI scanner environment
TLDR
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. Expand
Quantitative meta-analysis identifies brain regions activated during rectal distension in irritable bowel syndrome.
TLDR
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. Expand
Electrophysiological investigation of the contribution of attention to altered pain inhibition processes in patients with irritable bowel syndrome
TLDR
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. Expand
The balancing act: endogenous modulation of pain in functional gastrointestinal disorders
TLDR
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. Expand
Thicker posterior insula is associated with disease duration in women with irritable bowel syndrome (IBS) whereas thicker orbitofrontal cortex predicts reduced pain inhibition in both IBS patients and controls.
TLDR
IBS patients showed thicker right posterior insula, associated with longer disease duration but not with psychological symptoms, which suggests that IBS induces thickening of pINS, which may contribute to its pathophysiology, consistent with the role of the pINS in interoception and pain. Expand
Widespread hypersensitivity is related to altered pain inhibition processes in irritable bowel syndrome
TLDR
The relation between altered pain inhibition processes and widespread hypersensitivity in IBS confirms the relation between visceral hypersensitivity, cutaneous thermal sensitivity, and central pain mechanisms, and covariance analyses indicated that psychological factors accounted for group differences in visceral hypers sensitivity and pain inhibition deficits.

Brain functional magnetic resonance imaging of rectal pain and activation of endogenous inhibitory mechanisms in irritable bowel syndrome patient subgroups and healthy controls
TLDR
IBS-C and IBS-D appear to have differing abnormal endogenous pain inhibitory mechanisms, involving DNIC and other supraspinal modulatory pathways. Expand
Central processing of rectal pain in patients with irritable bowel syndrome: an fMRI study
TLDR
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. Expand
Regional cerebral activation in irritable bowel syndrome and control subjects with painful and nonpainful rectal distention.
TLDR
Functional magnetic resonance imaging data suggest heightened pain sensitivity of the brain-gut axis in IBS, with a normal pattern of activation. Expand
Differences in brain responses to visceral pain between patients with irritable bowel syndrome and ulcerative colitis
TLDR
Functional connectivity analyses showed that right lateral frontal cortex (RLFC) activation positively correlated with activation of the dorsal pons/periaqueductal gray, a key region involved in endogenous pain inhibition, which is not necessarily associated with increased visceral afferent input to the brain during rectal distension. Expand
Alteration of the spinal modulation of nociceptive processing in patients with irritable bowel syndrome
TLDR
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. Expand
Abnormal forebrain activity in functional bowel disorder patients with chronic pain
TLDR
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. Expand
Repetitive sigmoid stimulation induces rectal hyperalgesia in patients with irritable bowel syndrome.
TLDR
In patients with IBS, repetitive stimulation of sigmoid splanchnic afferents results in the development of central sensitization manifested as hyperalgesia and increased viscerosomatic referral during rectal distention and as spontaneous rectosigmoid hyperalGESia in the absence of applied stimuli.

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. Expand
Regional cerebral activity in normal and pathological perception of visceral pain.
TLDR
The perception of acute rectal pain is associated with activation of the anterior cingulate cortex in healthy subjects, and patients with IBS show an aberrant brain activation pattern both during noxious rectal distention and during the anticipation ofrectal pain. Expand

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