Placebo-analgesic Neurotransmitters
The placebo effect caused by pre-administration of different painkillers can be formed with the participation of different neurotransmitters-substances that provide signal transmission between nerve cells. It hides not one, but several different mechanisms that reflect the General principles of the nervous system, but implemented in different ways. A few years after experiments with stimulation, the main neurotransmitters of this phenomenon were found in laboratory rodents of the Central gray matter. They turned out to be endorphins, enkephalins, and a number of other substances called endogenous opioids. Their molecules have areas similar to those of the plant opioid morphine, so that all these substances can bind to opioid receptors, causing pain relief. Both short-term stress-induced pain relief and longer-term pain relief, which occur in response to almost any pain, are associated…
