First, opiate receptors were discovered and their distribution throughout the central nervous system mapped. Then endogenous morphine-like compounds, called endorphins and enkephalins, were identified. One of the most promising aspects of understanding the physiology and pharmacology of these endogenous opiates is conquering control over pain.
