Apart from these more specialized uses of the medium, scientists and physicians also sought to use it as a tool of popular enlightenment and a means of educating the public on a variety of scientific and hygienic themes. Such projects reflected the post-World War I realization of film's immense potential for reaching broad audiences. In the 1920s, for instance, the Soviet Studio for Popular-Scientific Film produced the film "Bedingte Reflexe bei Tieren" ("Conditioned Reflexes in Animals"), combining live action with animation and featuring Pavlov explaining the principle of the conditioned reflex (see also Vöhringer. 2001. Pudovkin's "Mechanics of the brain").
