The outworn terms vagotonia and sympathicotonia are still being used, and the vegetative nervous system is still being investigated by means of various pharmaceutic preparations.In the clinic of neurology at the university, we have adopted a method of studying the motility and the reflexes of the sympathetic system similar to that in use for the somatic system.
