Placebo Effect - Neurobiological Mechanisms

Placebo Effect - Neurobiological Mechanisms

Here the neurobiology of placebo effects is considered in terms of opioid and non-opioid mechanisms.

Experimental studies have revealed that placebo effects occur at specific body regions and this process involves the release of highly specific endogenous opioids.

Many placebo effects are also mediated by non-opioid mechanisms such as different neurotransmitters and neuromodulators.

The exact neurobiological mechanisms of placebo effects are little understood.
