Endorphins discovered

Endorphins discovered

1972

The morphine-like chemicals in the brain called endorphins are discovered. John Hughes and Hans Kosterlitz of Scotland isolate from the brain of a pig what they called enkephalins and will later be termed 'endorphin' from an abbreviation of 'endogenous morphine'. These are polypeptides produced by the pituitary gland and the hypothalamus in vertebrates, and they resemble opiates in their abilities to produce analgesia and a sense of well-being. In other words, they might work as natural pain killers.
