Italian neurologist Vincenzo Neri was able to discover cinematography at the beginning of his career, when in 1908 he went to Paris to learn and improve his clinical background by following neurological cases at La Pitié with Joseph Babinski, who became his teacher and friend. While in Paris, Neri photographed and filmed several patients of famous neurologists, such as Babinski and Pierre Marie. His stills were published in several important French neurological journals and medical texts. He also collaborated with Georges Mendel, who helped Doyen film the first known surgical operation in the history of cinema. In 1910, when he came back to Bologna, he continued in his clinical activities and, for 50 years, slowly developed a huge archive of films, images, and prints of neurological, psychiatric, and orthopedic cases. This archive was extremely helpful to Neri, who especially needed to analyze neurological disorders and to differentiate them from functional conditions in order to understand clinical signs, rules, and mechanisms.

Violins are complex wooden musical instruments, whose quality is mainly evaluated on the basis of their aesthetics, as well as depending on the historical relevance of their makers. However their acoustic quality remains a key evaluation parameter for performers and listeners. The instrument perceived quality, in turn, depends, on one side, on the player, the environmental conditions and on the listeners' psychoacoustic factors. On the other side, the quality of a violin depends on its materials, constructive and setup parameters, that impact on the vibro-acoustical characteristics of the instrument. This work investigates a procedure for the vibro-acoustic characterization of a violin, here called vibro-acoustic fingerprint, as an example of vibro-acoustical characterization of a wooden music instrument. The procedure was applied, as a case study, to an Italian contemporary violin, built in the year 2011 by the violin-maker Enzo Cena on a Guarneri del Gesù model.
