Emotions have powerful effects on pain perception. However, the brain mechanisms underlying these remain largely unknown. In this study, we combined functional cerebral imaging with psychophysiological methods to explore neural involved in emotional modulation of spinal nociceptive responses (RIII-reflex) and perception healthy participants. induced by pleasant or unpleasant pictures modulated painful electrical stimulations right insula, paracentral lobule, parahippocampal gyrus, thalamus,...
Pain is a complex experience involving extensive interactions between brain and spinal cord processes. Various interventions that modulate pain, such as the application of competing noxious stimulus (counterirritation), are thought to involve cerebrospinal regulation through diffuse inhibitory controls (DNICs). However, no study has yet examined relation activity during counterirritation analgesia in humans. This fMRI investigates responses phasic painful electrical stimulation administered...
The mechanisms of chronic pain in irritable bowel syndrome (IBS) have been widely investigated but remain unclear. present study the relation between visceral hypersensitivity, cutaneous thermal sensitivity, and central mechanisms. Rectal sensitivity was assessed with a barostat, forearm calf contact thermode. Central were by counterirritation using sustained cold-pain to hand painful electric shocks ankle. Psychological symptoms also assessed, questionnaires. Female volunteers...
In the past two decades, functional brain imaging has considerably advanced our knowledge of cerebral pain processing. However, many important links are still missing in understanding activity relation to regulation pain-related physiological responses. This fMRI study investigates correlates (rating), motor responses (RIII-reflex) and autonomic (skin conductance response; SCR) evoked by noxious electrical stimulation. Stimulus intensity was adjusted individually based on RIII threshold...
Summary Pain inhibitory descending control efficiency decreases with healthy aging, and it is significantly correlated a decrease in the efficacy of cognitive inhibition. The analgesic effect heterotopic noxious counter-stimulation (HNCS; “pain inhibits pain”) has been shown to older persons, while some neuropsychological studies have suggested reduction inhibition normal aging. Taken together, these findings may reflect generalized processes. present study assessed whether decline pain...
Heterotopic noxious counterstimulation (HNCS) by the application of a sustained stimulus has been shown to inhibit nociceptive processes and decrease pain induced competing stimulus. However, it is still not clear how attentional contribute these effects. The main objective this study was compare analgesic effects HNCS in 2 sessions during which top-down attention manipulated. Acute shock flexion reflex were evoked transcutaneous electrical stimulations right sural nerve 4 blocks (15...
The aim of this study was to examine whether transcranial direct current stimulation (tDCS) the dorsolateral prefrontal cortex (DLPFC) enhances pain inhibition by improving working memory (WM). Forty healthy volunteers participated in two tDCS sessions. Pain evoked electrical at ankle. Participants performed an n-back task (0-back and 2-back). experimental protocol comprised five counterbalanced conditions (0-back, 2-back, pain, 0-back with 2-back pain) that were twice (pre-tDCS baseline...
Introduction: The presence of altered central pain processing and modulation, as well negative psychological factors, have been suggested to impede recovery in chronic low back (CLBP). Psychologically-informed physiotherapy (PiP) aims specifically address the latter factors—in addition physical factors—to improve treatment effects. This study determine if effect PiP is superior usual (UP) on sensitivity modulation participants with CLBP changes these variables were associated clinical...
The Personal Attributes Questionnaire (PAQ) assesses gender roles, including expressivity (femininity) and instrumentality (masculinity), which reflect socially culturally defined feminine masculine ways of thinking, feeling, behaving. PAQ allows the assessment gendered traits, beyond traditional binary view. With inclusion gender-related factors in various research fields, has been validated multiple languages cultures, German, Chinese, French. However, a Persian version not yet validated....
Demanding tasks can influence following behaviors but the underlying mechanisms remain largely unclear. In present functional magnetic resonance imaging (fMRI) study, we used multivariate pattern analyses (MVPA) to compare patterns of brain activity associated with pain in response noxious stimuli administered after a task requiring cognitive control (Stroop) and evaluate their interaction based on mediation analysis model. We found that performing difficult leads subsequent increases...
