痛覚のSpecific TheoryとGeneral Theoryのうつりかわり

Changes in pain theory

　痛みの問題は医学の原点ともいうべきものであり，この問題の探求に費された努力は膨大な量にのぼるが，他の感覚系にくらべ，その不明瞭度は著しく高い。

Since the adequate stimuli for pain are 'noxious' as defined by Sherrington, which means 'threat-ening to damage the tissues', the body receiving such a stimulation should react with all recruit-ments of various organizations in the body. This induces a vague and complicated nature in pain phenomena. Reflecting this characteristic, theory on pain is still fluctuating now.
