PLACEBO ANALGESIA 1 Placebo Analgesia
SUMMARY The expectation of pain relief can exert a powerful analgesic effect, even when pain is severe. Depending on the nature of experiences and instructions provided, a placebo analgesic effect can be elicited acutely in a very large percentage of individuals, in both experimental and clinical contexts. Placebo analgesia has been linked with activity in the prefrontal cortex, endogenous opio...
متن کاملCentral inhibition and placebo analgesia
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. In the case of activity detected during conscious processes, such as pl...
متن کاملPlacebo‐like analgesia via response imagery
BACKGROUND Placebo effects on pain are reliably observed in the literature. A core mechanism of these effects is response expectancies. Response expectancies can be formed by instructions, prior experiences and observation of others. Whether mental imagery of a response can also induce placebo-like expectancy effects on pain has not yet been studied systematically. METHODS In Study 1, 80 heal...

متن کاملPlacebo Analgesia: A Predictive Coding Perspective
This Perspective reviews recent findings in placebo hypoalgesia and provides a conceptual account of how expectations and experience can lead to placebo hypoalgesia. In particular, we put forward the idea that the ascending and the descending pain system resembles a recurrent system that allows for the implementation of predictive coding-meaning that the brain is not passively waiting for nocic...
