Introduction to symposium on endorphins and behavioural processes; review of literature on endorphins and exercise

Pharmacol Biochem Behav. 1985 Nov;23(5):857-62. doi: 10.1016/0091-3057(85)90083-8.


The first symposium on endorphins and behavioural processes in Britain was held by the British Psychological Society in March 1985. Against a background of the explosive history of the discovery of endogenous opioids, problems of terminology, and basic mechanisms and concepts, five papers reflect the main fields in which outstanding progress has been made: analgesia, feeding, reward mechanisms, social behaviour and aggression, and addiction. A review of the literature on endorphins and exercise stresses both the value and limitations of trying to unravel a fashionable subject. Endorphin research is multi-disciplinary and highly complex, with tricky technical and conceptual problems and inevitable lack of consensus. Investigators should be more aware of the crucial role that outcomes of behaviour experiments play in the attribution of function to opioid systems.
