Paul Emil Flechsig (29 June 1847 in Zwickau – 22 July 1929 in Leipzig, Germany) was an eminent nineteenth-century German neuroanatomist, psychiatrist and neuropathologist.
Professor Flechsig had an interest in myelinogenesis — the development of the myelin sheaths for nerves.[1] The myelin acts as an insulator to allow the electrical impulses to travel through the nerves.[1]
Flechsig (1872) observed that the myelin sheath is not yet formed in newborn babies,[2] so he came to the unfounded conclusion that the newborn cannot feel pain.[3] So great was his reputation and influence that his views were accepted without question, even though empirical studies had not been carried out. Surgical operations were carried out on infants without pain medication.
Flechsig views are disproved
It was not until a century that medical science started to question his views. Talbert et al. (1976) measured the rise in cortisol and cortisone in circumcised infants and found an increase in "stress".[4] Gunnar et al. (1981) also examined serum cortisol and behavior after neonatal circumcision. They reported "striking increases in serum cortisol concentrations" after unanesthetized circumcision.[5]
