Temporal structure of brain oscillations predicts learned nocebo responses to pain [PDF]
Scientific Reports, 2021 AbstractThis study aimed to identify electrophysiological correlates of nocebo-augmented pain. Nocebo hyperalgesia (i.e., increases in perceived pain resulting from negative expectations) has been found to impact how healthy and patient populations experience pain and is a phenomenon that could be better understood in terms of its neurophysiological ...

Nonconscious activation of placebo and nocebo pain responses [PDF]
Proceedings of the National Academy of Sciences, 2012 The dominant theories of human placebo effects rely on a notion that consciously perceptible cues, such as verbal information or distinct stimuli in classical conditioning, provide signals that activate placebo effects. However, growing evidence suggest that behavior can be triggered by stimuli presented outside of conscious awareness.

Placebo and the law of identification [PDF]
Frontiers in PsychiatryThousands of essays and studies have been published on placebo and nocebo. Yet, despite this plethora of information, we are not much closer to a comprehensive understanding of the fundamental mechanism producing placebo and nocebo effects than we were ...

Placebo and Nocebo Effects Are Defined by Opposite Opioid and Dopaminergic Responses [PDF]
Archives of General Psychiatry, 2008 Placebo and nocebo effects, the therapeutic and adverse effects, respectively, of inert substances or sham procedures, represent serious confounds in the evaluation of therapeutic interventions. They are also an example of cognitive processes, particularly expectations, capable of influencing physiology.To examine the contribution of 2 different ...

PO104 Placebo and nocebo responses in rls: a meta-analysis [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 2017 Objective Our goals were to estimate the placebo and nocebo responses in restless legs syndrome (RLS). Methods Databases were searched up to October 2015. Randomised, double-blind, placebo-controlled trials of RLS patient were included. ‘Placebo response’ was defined as the within-group change from baseline, using any scale measuring RLS severity or

Chicken or egg? Attribution hypothesis and nocebo hypothesis to explain somatization associated to perceived RF-EMF exposure [PDF]
Frontiers in Public HealthIntroductionThe aim of this study is to understand the temporal relationship between the somatization usually attributed to RF-EMFs, and to evaluate the attribution hypothesis and the nocebo hypothesis in this context.MethodIn this longitudinal study ...

Understanding Placebo and Nocebo Responses for Pain Management [PDF]
Current Pain and Headache Reports, 2014 Placebo analgesia makes individuals experience relief of their pain simply by virtue of the anticipation of a benefit. A reduction of pain can occur also when placebos follow the administration of active and effective painkillers. In fact, studies indicate that placebos mimic the action of active treatments and promote the endogenous release of opioids

Does electromagnetic hypersensitivity originate from nocebo responses? Indications from a qualitative study [PDF]
Bioelectromagnetics, 2015 Idiopathic Environmental Intolerance attributed to Electromagnetic Fields (IEI‐EMF) is a condition in which symptoms are attributed to electromagnetic field (EMF) exposure. As electro‐hypersensitive (EHS) people have repeatedly been observed, during provocation trials, to report symptoms following perceived rather than actual exposure, the hypothesis ...
