If the lesion is proximal to the geniculation ganglion, the motor paralysis is accompanied by gustatory and autonomic abnormalities, while lesion between the geniculate ganglion and the origin of chorda tympani produces same effects, except that lacrimation is spared.

Although he was only 34 years old, he had accumulated experimental practice: on the chorda tympani (Olmsted and Olmsted, 1952: 34), the action of curare (Changeux, in Robin, 1979: 73-95), he had catheterised the heart to measure the heart blood pressures and the heat production by the lungs (Cournand, in Robin, 1979: 97-121).
