Objectives: This paper aims to determine if hypnotic analgesia suggestion and transcranial direct-current stimulation (tDCS) have a differential effect on pain perception. We hypothesized that transcranial direct-current stimulation would be more effective than hypnotic analgesia suggestion at changing the descending pain modulating system, whereas the hypnotic suggestion would have a greater effect in quantitative sensory testing. Design: This is a randomized, double blind and crossover trial… Expand
Effect of High-definition Transcranial Direct Current Stimulation on Conditioned Pain Modulation in Healthy Adults: A Crossover Randomized Controlled Trial
HD-tDCS significantly improved the analgesic efficiency of Δ-CPM, compared with the sham control, after adjusting the confounding factors including age, gender, psychological status, as well as the sequence effect. Expand
The Hypnotic Analgesia Suggestion Mitigated the Effect of the Transcranial Direct Current Stimulation on the Descending Pain Modulatory System: A Proof of Concept Study
Findings indicate that the HS combined with a-tDCS mitigated the effect of the a- tDCS on the DPMS and enhanced the reaction time substantially upon the CPT. Expand
Role of the Anterior Cingulate Cortex in Translational Pain Research.
The ACC is summarized as a new central neuromodulation target for invasive and non-invasive stimulation techniques in clinical pain management and the comprehensive understanding of pain processing in the ACC may lead to bridging the gap in translational research between basic and clinical studies and to develop new therapies.

From Mechanisms to Analgesia: Towards the Use of Non-Invasive Neuromodulation for Pain Relief in the Clinic
This review will focus on the application of electric currents non-invasively to different sites for pain relief and outline the future potential of these technologies. Expand
Can there be delusions of pain
Abstract: Jennifer Radden argues that there cannot be delusional pain in depression, putting forward three arguments: the argument from falsehood, the argument from epistemic irrationality, and theExpand


Anodal transcranial direct current stimulation over the left dorsolateral prefrontal cortex modulates attention and pain in fibromyalgia: randomized clinical trial
Regression analysis showed that DLPFC may be an important target for neurostimulation therapies in addition to the primary motor cortex for patients who do not respond adequately to neuro Stimulation therapies. Expand
Effects of hypnosis on diffuse noxious inhibitory controls
It seems likely that DNICs and hypnosis use the same descending inhibitory pathways for the control of pain, and both hypnosis andDNICs were able to modify the perception of pain. Expand
Effects of transcranial direct current stimulation on pain perception and working memory
The present data show an involvement of the DLPFC in the processing of pain and WM, suggesting that the analgesic effects of cortical stimulation are not associated with cognitive processing. Expand
Repetitive transcranial magnetic stimulation of dorsolateral prefrontal cortex increases tolerance to human experimental pain.
Results show that 1 Hz rTMS of right DLPFCx has a selective effect by increasing pain tolerance and also sustains a right hemisphere preference in pain processing. Expand
Noninvasive cortical modulation of experimental pain
Whether the results obtained in experimental pain can be transposed to the problem of chronic pain and whether they can be used to optimize cortical stimulation therapy for pain disorders is discussed. Expand
Fifteen minutes of left prefrontal repetitive transcranial magnetic stimulation acutely increases thermal pain thresholds in healthy adults.
The idea that the left prefrontal cortex may be a promising TMS cortical target for the management of pain is supported, as a significant increase in thermal pain thresholds following TMS is demonstrated. Expand
A meta-analysis of hypnotically induced analgesia: How effective is hypnosis?
Meta-analysis of 18 studies revealed a moderate to large hypnoanalgesic effect, supporting the efficacy of hypnotic techniques for pain management and indicating that hypnotic suggestion was equally effective in reducing both clinical and experimental pain. Expand
Cognitive effects of transcranial direct current stimulation combined with working memory training in fibromyalgia: a randomized clinical trial
The combination of both techniques seemed to produce effects on specific cognitive functions related to short-term and long-term episodic memory and executive functions, which has clinical relevance for top-down treatment approaches in FM. Expand
An electrophysiological investigation into the pain-relieving effects of heterotopic nociceptive stimuli. Probable involvement of a supraspinal loop.
The results show that the effects of heterotopic nociceptive stimulation observed in normal man are possibly mediated by a complex loop involving supraspinal structures and underlines the similarity between this phenomenon and the Diffuse Noxious Inhibitory Controls described in the rat. Expand
Diffuse analgesic effects of unilateral repetitive transcranial magnetic stimulation (rTMS) in healthy volunteers
It is demonstrated that unilateral rTMS of M1 or DLPFC induces diffuse and selective analgesic effects in healthy volunteers, and the lack of effect on the RIII reflex suggests that such analgesics effects may not depend on the activation of descending inhibitory systems. Expand
