Significant age and experience-dependent remodelling of spinal and supraspinal neural networks occur resulting in altered pain responses in early life. In adults endogenous opioid peptide and endocannabinoid (ECs) pain control systems exist which mod...

Scientific Reports, 7, Article 10748. https://doi.org/10.1038/s41598-017-09516-3

Resolvins are omega-3 fatty acid derived potent bioactive lipids that resolve inflammation and modulate transient receptor potential channels. Exogenous administration of the resolvin precursor 17-HDHA shows a strong analgesic effect in animal models...

Manganese-enhanced magnetic resonance imaging depicts brain activity in models of acute and chronic pain: a new window to study experimental spontaneous pain? (2017)
Journal Article
Devonshire, I. M., Burston, J., Xu, L., Lillywhite, A., Prior, M., Watson, D. J., …Chapman, V. (2017). Manganese-enhanced magnetic resonance imaging depicts brain activity in models of acute and chronic pain: a new window to study experimental spontaneous pain?. NeuroImage, 157, https://doi.org/10.1016/j.neuroimage.2017.06.034

Application of functional imaging techniques to animal models is vital to understand pain mechanisms, but is often confounded by the need to limit movement artefacts with anaesthesia, and a focus on evoked responses rather than clinically relevant sp...
