Modulatory role of intra-accumbal dopamine receptors in the restraint stress-induced antinociceptive responses.

Stress contributes to pain sensation by affecting several neural pathways, including mesolimbic-cortical dopamine neurons. Nucleus accumbens, an essential element of the mesolimbic dopaminergic pathway, plays a fundamental role in modulating […]

Alteration of brain network centrality in CTN patients after a single triggering pain.

The central nervous system may also be involved in the pathogenesis of classical trigeminal neuralgia (CTN). The present study aimed to explore the characteristics of static degree centrality (sDC) and […]

Can we characterize A-P/IAP behavioural phenotypes in people with chronic pain?

Two behavioural phenotypes in healthy people have been delineated based on their intrinsic attention to pain (IAP) and whether their reaction times (RT) during a cognitively-demanding task are slower (-type) […]

New techniques and methods for prevention and treatment of symptomatic traumatic neuroma: A systematic review.

Generally, axons located at the central end of the nerve system will sprout after injury. Once these sprouts cannot reach the distal end of the severed nerve, they will form […]

Properties of Nav1.8-positive and Nav1.8-negative afferent mechanoreceptors in the hindpaw glabrous skin of mice.

Nav1.8-positive afferent fibers are mostly nociceptors playing a role in mediating thermal and mechanical pain, but mechanoreceptors within these afferents have not been fully investigated. In this study, we generated […]

Musculoskeletal pain patterns and association between dizziness symptoms and pain in patients with long term dizziness – a cross-sectional study.

The impact of long-term dizziness is considerable both on the personal level and in society and may lead to self-imposed restrictions in daily activities and social relations due to fear […]

Left- vs right-sided migraine: a scoping review.

Migraine is a historically unilateral head pain condition, the cause of which is not currently known. A growing body of literature suggests individuals who experience migraine with left-sided headache (“left-sided […]

Defining metabolic migraine with a distinct subgroup of patients with suboptimal inflammatory and metabolic markers.

Emerging evidence suggest migraine is a response to cerebral energy deficiency or oxidative stress in the brain. Beta-hydroxybutyrate (BHB) is likely able to circumvent some of the meta-bolic abnormalities reported […]

Transcranial direct current stimulation to reduce chronic pelvic pain in endometriosis: Phase II Randomized Controlled Clinical Trial.

It is known that various chronic pain conditions lead to maladaptive changes in the central nervous system. Endometriosis is frequently associated with chronic pelvic pain (CPP). Its sufficient treatment remains […]

Alterations of pain pathways by experimental sleep disturbances in humans: Central pain-inhibitory, cyclooxygenase, and endocannabinoid pathways.

There is strong evidence that sleep disturbances are an independent risk factor for the development of chronic pain conditions. The mechanisms underlying this association, however, are still not well understood. […]
