Expectations: How and When Do They Contribute to Placebo Analgesia? [PDF]
Frontiers in Psychiatry, 2022 In placebo research, expectations are highlighted as one of the most influential subjective factors. While some studies have shown a relationship between expectations and pain relief, others have not.

Meta-analysis of neural systems underlying placebo analgesia from individual participant fMRI data [PDF]
Nature Communications, 2021 The neural mechanisms of placebo analgesia are not fully understood. Here the authors conducted a large scale meta-analysis of individual data from fMRI studies of pain and placebo conditions.

Reverse-Engineering Placebo Analgesia [PDF]
Current BiologySUMMARY Placebo analgesia is a widely observed clinical phenomenon. Establishing a robust mouse model of placebo analgesia is needed for careful dissection of the underpinning circuit mechanisms.

Stimulus-independent and stimulus-dependent neural networks underpin placebo analgesia responsiveness in humans [PDF]
Communications Biology, 2023 The neural circuits that regulate placebo analgesia responsivity are unknown, although engagement of brainstem pain modulatory regions is likely critical.

A Social Affective Neuroscience Lens on Placebo Analgesia [PDF]
Trends in Cognitive Sciences, 2021 Pain is a fundamental experience that promotes survival. In humans, pain stands at the intersection of multiple health crises: chronic pain, the opioid epidemic, and health disparities. The study of placebo analgesia highlights how social, cognitive, and

Distinct neural networks subserve placebo analgesia and nocebo hyperalgesia
NeuroImage, 2021 Neural networks involved in placebo analgesia and nocebo hyperalgesia processes have been widely investigated with neuroimaging methods. However, few studies have directly compared these two processes and it remains unclear whether common or distinct ...

One of us or one of them? The effects of the model's and observer's characteristics on placebo analgesia induced by observational learning. [PDF]
PLoS ONE, 2020 Previous studies have proved that observational learning can induce placebo analgesia, but the factors that influence observationally induced placebo analgesia have not yet been extensively examined.

Неврология, нейропсихиатрия, психосоматика, 2018 Placebos are drugs, devices, or other treatments that are physically and pharmacologically inert. The placebo effects are therapeutic responses to the context of the treatment process.

Central inhibition and placebo analgesia
Molecular Pain, 2005 Most neuroscientists measure neuronal activity in the brain to predict or explore the contribution of neurons to physiological/pathological functions of the brain. For example, if an increase in neuronal activity is detected in one brain region by peripheral noxious stimuli, we call this area the pain region or pain matrix.

Journal of Pain, 2021 The aim of this study was to investigate the effect on observationally acquired placebo analgesia of a model's self-confidence as well as the observer's self-esteem and self-efficacy.
