Investigating the Influence of Experimentally Induced Secondary Hyperalgesia on Pain Prediction Error Encoding in Healthy Individuals: A Novel Virtual Reality Protocol

open access: yesEuropean Journal of Pain, Volume 29, Issue 9, October 2025.
ABSTRACT Background Persistent mismatches between predicted and actual pain‐related signals, namely prediction errors (PEs), can cause maladaptive overestimation of pain intensity, a common feature of chronic pain states. Experimental protocols used to assess the contribution of central sensitisation (CS) to dysregulated prediction systems are lacking.

Nocebo Responses in Brain Diseases: A Systematic Review of the Current Literature

open access: yes, 2018
Placebo is an intervention with no therapeutic effect that is used as a control in randomized controlled trials (RCTs). Placebo effects and responses can produce a beneficial effect that cannot be attributed to the properties of the intervention itself, since it is usually inactive, and should, therefore, be due to the patient's expectations about ...
