Tram Driver Undergoes Nerve Test

(Original Caption) Nerve test for the road electric tram drivers. Frankfurt, 11.11.1953. The Frankfurt Transport introduced recently into use a new apparatus, a so called 'neuroscope' used for the nerve test of the electric tram drivers. The patient doesn't need to reply to any question but just to sit quietly and keep an electrode in his hand while the other one is pressed to about 200 reaction points by the doctor and on a special diagram the doctor or psychiatric specialist can read the results. Picture shows Ing. C.A. Hoehle who works for 28 years on this kind of neuroscope apparatus during a test. (Photo by © Hulton-Deutsch Collection/CORBIS/Corbis via Getty Images)
