Purpose of review The understanding of the mechanisms underlying chronic pain is of major scientific and clinical interest. This review focuses on neuroimaging studies of pain-induced neuroplastic changes in the human brain and discusses five major categories of pain-induced neuroplastic changes. Recent findings First, peripheral or central sensitization may result in increased nociceptive input to the brain and also changes the processing of nociceptive information within the brain. Second… Expand
Neurophysiological Principles of Brain Stimulation in Pain Management
The mature human brain is capable to undergo substantial long-lasting functional and structural changes of neural pathways and synapses due to changes in behavior, previous experience, physiologicalExpand
Pharmacological modulation of brain activity in a preclinical model of osteoarthritis
TLDR
An assessment of brain function may provide an objective means by which to further evaluate the pathology of an osteoarthritis state as well as measure the pharmacodynamic effects of therapies with peripheral or peripheral and central pharmacological action. Expand
Characterization of incisional and inflammatory pain in rats using functional tools of MRI
TLDR
It is concluded that employment of MS in fMRI studies could provide an informative correlate of mechanical hyperalgesia in inflammatory and incisional pain models and might be used to further assess mechanisms and treatments relevant for these clinical pain states. Expand
Therapeutic time window of noninvasive brain stimulation for pain treatment: inhibition of maladaptive plasticity with early intervention
TLDR
The authors discuss the potential role of NIBS in blocking maladaptive plasticity using the transition of acute to chronic pain in conditions such as postsurgical pain, central poststroke pain, pain after spinal cord injury and pain after traumatic brain injury as a model. Expand
Decision making in the chronic pain patient (and rodent): Contribution of the orbitofrontal cortex
TLDR
A study that links risk-prone decision making in rats with chronic inflammatory pain to neuronal activity in the orbitofrontal cortex is described, which takes advantage of the recent development of a rodent task that models some features of the Iowa gambling task. Expand
Surgically Induced Neuropathic Pain: Understanding the Perioperative Process
TLDR
New technologies including direct measures of specific brain function of nociception and new insights into preoperative evaluation of patients including genetic predisposition appear to provide initial opportunities for decreasing the burden of SNPP, until treatments with high efficacy and low adverse effects that either prevent or treat pain are discovered. Expand
Altered evoked low-frequency connectivity from SI to ACC following nerve injury in rats
TLDR
It is shown that both a directed and non-directed connectivity between SI and ACC approach can be used to show the acute changes resulting from the SNI model, likely indicating hypersensitivity of this pathway. Expand
The origins of pain in diverticular disease: peripheral or central?
This study was designed to identify the processes which underlie pain in symptomatic diverticular disease (SDD). Our hypothesis was that a spectrum of both peripheral and central pathologies wereExpand
Distinctive neural responses to pain stimuli during induced sadness in patients with somatoform pain disorder: An fMRI study☆
TLDR
FMRI results suggest that a negative emotional context such as sadness contributes to dysfunctional pain processing in somatoform pain disorder, and greater sensitivity to low levels of pain in an emotional context of sadness might be an important aspect of the psychopathology of somatoforms pain disorder. Expand
The clinical utility of repetitive transcranial magnetic stimulation in reducing the risks of transitioning from acute to chronic pain in traumatically injured patients
TLDR
This review will first discuss the contribution of neuroinflammation and central sensitization in the transition from acute to chronic pain in traumatically injured patients, and provide a theoretical framework of what might constitute optimal rTMS modalities based on an integrated perspective of the physiopathological mechanisms underlying pain.

Imaging pain modulation in health and disease
TLDR
Recent findings from functional and anatomical neuroimaging support the notion that an altered interaction of pro and antinociceptive mechanisms may contribute to the development or maintenance of chronic pain states. Expand

TLDR
Cerebral processing in experimental pain models, especially those provoking hyperalgesia, and its pharmacological modulation will form the first part of a review of mechanisms of clinical neuropathic pain. Expand
Brain imaging of neuropathic pain
TLDR
Overall, these studies indicated that acute physiological pain and neuropathic pain have distinct although overlapping brain activation pattern, but that there is no unique "pain matrix" or "allodynia network". Expand
Neuroimaging revolutionizes therapeutic approaches to chronic pain
TLDR
It should now be considered an altered brain state in which there may be altered functional connections or systems and a state that has components of degenerative aspects of the CNS. Expand

TLDR
Any data of an increase or decrease in gray matter in pain syndromes need to be considered in light of all observations gathered in the past 10 years and probably do not justify a discussion of brain damage or consideration of whether the disease is progressive. Expand

Brain Gray Matter Decrease in Chronic Pain Is the Consequence and Not the Cause of Pain
TLDR
It is suggested that the gray matter abnormalities found in chronic pain do not reflect brain damage but rather are a reversible consequence of chronic nociceptive transmission, which normalizes when the pain is adequately treated. Expand
Mechanisms of central neuropathic pain: a combined psychophysical and fMRI study in syringomyelia.
TLDR
No significant difference was found in the magnitude or extent of sensory deficits between patients with or without neuropathic pain, suggesting that lesions of the spinothalamic pathways are not sufficient for developing central pain. Expand

TLDR
It is found that the magnitude of activation in the caudal anterior insula (cAI) correlates with the perceived intensity of allodynic pain across subjects, independent of the level of ongoing pain. Expand
