A better understanding of the neural mechanisms underlying pain processing and analgesia may aid in the development and personalization of effective treatments for chronic pain. Clarification of the neural predictors of individual variability in placebo analgesia (PA) could aid in this process. The present study examined whether the strength of effective connectivity (EC) among pain-related brain...
Although placebo analgesia has been associated with an engagement of the endogenous opioid system there is growing evidence from neuropharmacological studies for an involvement of additional neurotransmitter systems. An increased dopaminergic neurotransmission in the ventral basal ganglia that has been found during placebo analgesia suggests a role for the dopaminergic system (Scott et al., 2007)...
The effectiveness of placebo treatments depends on the recipient's expectations, which are at least in part shaped by previous experiences. Thus, positive past experience together with an accordant verbal instruction should enhance outcome expectations and subsequently lead to higher placebo efficacy. This should be reflected in subjective valuation reports and in activation of placebo-related brain...
