| Source | Participants | Methods | Major findings |
|---|---|---|---|
| (A) ‘Presentation of the gate control theory of pain’ | |||
| Brügger et al. (2012) | Healthy adults | fMRI | ‘Cerebral toothache intensity coding on a group level can thus be attributed to specific subregions within the cortical pain network’. |
| Gustin et al. (2011) | TNP and TMD patients | sMRI, MRS | ‘…neuropathic pain conditions that result from peripheral injuries may be generated and/or maintained by structural changes in regions such as the thalamus’ |
| (B) ‘… the multidimensionality and biopsychosocial aspects of pain and their application to improved diagnosis and management of orofacial pain conditions’ | |||
| Youssef et al. (2014) | Painful TN and TMD patients | ASL‐MRI | ‘… non‐neuropathic pain was associated with significant CBF increases in regions commonly associated with higher‐order cognitive and emotional functions …’ |
| Weissman‐Fogel et al. (2011) | Patients with nontraumatic TMD | fMRI | ‘… the slow behavioural responses in idiopathic TMD may be due to attenuated, slower and/or unsynchronized recruitment of attention/cognition processing areas’. |
| (C) ‘Discovery of trigeminal nociceptive afferents and their modulation by processes within orofacial tissues …’/‘Discovery of the plasticity of the nociceptive neurons …’ | |||
| Gustin et al. (2012) | Patients with painful TN and painful TMD | fMRI, ASL‐MRI | ‘… while human patients with neuropathic pain displayed cortical reorganization and changes in somatosensory cortex activity, patients with non‐neuropathic chronic pain did not’. |
| Moayedi et al. (2012) | TMD patients | DTI | ‘… novel evidence for CNV microstructural abnormalities that may be caused by increased nociceptive activity, accompanied by abnormalities along central WM pathways in TMD’. |
| (D) ‘Discovery of nociceptive neurons in the brain and their modulation by intrinsic CNS circuits and endogenous mediators…’ | |||
| Desouza et al. (2013) | Patients with idiopathic trigeminal neuralgia | sMRI | ‘These findings may reflect increased nociceptive input to the brain, an impaired descending modulation system that does not adequately inhibit pain …’ |
| Abrahamsen et al. (2010) | TMD patients | fMRI | ‘… hypnotic hypoalgesia is associated with a pronounced suppression of cortical activity …’ |
| (E) ‘Definition of the central pattern generators for chewing and swallowing’ | |||
| Lowell et al. (2012) | Healthy adults | fMRI | ‘The greater connectivity from the left hemisphere insula to brain regions within and across hemispheres suggests that the insula is a primary integrative region for volitional swallowing in humans’. |
| Quintero et al. (2013) | Healthy adults | fMRI | ‘… demonstrated that brain activation patterns may dynamically change over the course of chewing sequences’. |
| (F) ‘… discovery of the plasticity of sensorimotor cortex and other CNS regions in relation to orofacial sensorimotor control, learning and adaptation to injury and other changes in orofacial tissues’ | |||
| Kimoto et al. (2011) | Edentulous patients wearing a CD and an IOD | fMRI | ‘…differential neural activity in the frontal pole within the prefrontal cortex between the two prosthodontic therapies – mandibular CD and IOD’. |
| Luraschi et al. (2013) | Edentulous patients wearing a CD | fMRI | ‘Changes in brain activity occurred in the adaptation to replacement dentures …’ |
| (G) ‘Delineation of peripheral processes and CNS circuits underlying touch, temperature, taste and salivation, including the discovery of a fifth taste, umami’ | |||
| Trulsson et al. (2010) | Healthy adults | fMRI | ‘… PDLMs, and SA II‐type receptors in general, may be involved in one aspect of the feeling of body ownership’. |
| Nakamura et al. (2011) | Healthy adults | fMRI | ‘The peaks of the activated areas in the middle insular cortex by umami were very close to another prototypical taste quality (salty)’. |
