100 Years since Robert Barany's visit to the Zaragoza medical faculty.

In December 1923, a twelve-day course took place at the University of Zaragoza, specifically at the Faculty of Medicine, given by Professor Róbert Bárány, who was awarded the Nobel Prize for Medicine in 1914 for his discoveries on the vestibular apparatus.Professor Robert Bárány came to the faculty at the invitation of Professor Victor Fairén through the University Exchange programme. This course consisted of four lectures and twelve lessons a day in which he presented his knowledge of the physiopathology of the vestibule and cerebellum, as well as practical demonstrations of the physical examination of nystagmus and cerebellar pathology.Lorente de Nó, a doctorate student of medicine, was one of the most outstanding students on the course. His intellect was already outstanding in those years, which helped him to discuss the physiopathology of nystagmus with Professor Bárány. The relationship he forged with the Nobel laureate in Zaragoza would be decisive for his future as a researcher.The aim of this work is to compile and integrate the available information on the course that Professor Bárány took in the city of Zaragoza, consulting official documents from the university and the city, articles, books and the press of the time.
