Challenges of differential placebo effects in contemporary medicine: The example of brain stimulation
Sign Up to like & getrecommendations! Published in 2019 at "Annals of Neurology"
DOI: 10.1002/ana.25387
Abstract: 'Differential placebo effects' is the concept that different types of placebos (e.g. inert pill versus sham device) may yield different magnitudes of placebo effects. This issue has been pushed into the spotlight by recent clinical… read more here.

Central correlates of placebo effects in nausea differ between men and women
Sign Up to like & getrecommendations! Published in 2022 at "Brain and Behavior"
DOI: 10.1002/brb3.2685
Abstract: Despite growing evidence validating placebo effects in nausea, little is known about the underlying cortical mechanisms in women and men. Therefore, the present study examined sex differences and electroencephalography (EEG) characteristics of the placebo effect… read more here.

DOI: 10.1007/s00482-022-00646-w
Abstract: BACKGROUND There are many studies on placebo analgesia and its underlying mechanisms that show a significant improvement of care for chronic pain patients. However, observational learning has not been researched to this degree. OBJECTIVES The goal… read more here.

DOI: 10.1016/j.neuroimage.2019.116510
Abstract: Learning through social observation is critical for humans. The present study investigates the neural processes underlying the acquisition of placebo effects through observational learning. We created a new functional magnetic resonance imaging (fMRI) paradigm where… read more here.

DOI: 10.1016/j.sjpain.2017.04.053
Abstract: Abstract Background Placebo effects are positive treatment effects that occur because of the psycho-social context around the therapy. Such effects are well documented in pain treatment, as well as in the treatment of other common… read more here.

Placebo effects in alternative medical treatments for anxiety: false hope or healing potential?

DOI: 10.1017/s1092852925100515
Abstract: Abstract Objective To investigate whether anxiety reductions attributed to healing crystals reflect placebo responses driven by conditioning and belief-related biases rather than specific therapeutic effects. Methods In a randomized, controlled study, 138 adults were classified… read more here.

DOI: 10.1038/s41467-023-44569-1
Abstract: Suggestions about hunger can generate placebo effects on hunger experiences. But, the underlying neurocognitive mechanisms are unknown. Here, we show in 255 women that hunger expectancies, induced by suggestion-based placebo interventions, determine hunger sensations and… read more here.

Uncertainty of treatment efficacy moderates placebo effects on reinforcement learning

DOI: 10.1038/s41598-024-64240-z
Abstract: The placebo-reward hypothesis postulates that positive effects of treatment expectations on health (i.e., placebo effects) and reward processing share common neural underpinnings. Moreover, experiments in humans and animals indicate that reward uncertainty increases striatal dopamine,… read more here.

Symptom perception, placebo effects, and the Bayesian brain

DOI: 10.1097/j.pain.0000000000001367
Abstract: 1. IntroductionThe standard and ideal biomedical model of symptom perception treats the brain largely as a passive stimulus-driven organ. It embraces the notion that the brain absorbs sensory signals from the body and converts them,… read more here.

How do placebo effects contribute to mindfulness-based analgesia? Probing acute pain effects and interactions using a randomized balanced placebo design.
Sign Up to like & getrecommendations! Published in 2022 at "Pain"
DOI: 10.1097/j.pain.0000000000002593
Abstract: ABSTRACT Recent sham-controlled studies suggest placebo effects contribute to acute pain relief following mindfulness interventions. However, the specific effects of mindfulness processes and their interaction with placebo effects remain unclear. This study aimed to characterize… read more here.

DOI: 10.1097/psy.0000000000000759
Abstract: ABSTRACT Objective There is evidence that placebo effects may influence hormone secretion. However, few studies have examined placebo effects in the endocrine system, including oxytocin placebo effects. We studied whether it is possible to trigger… read more here.
