Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
The Vulpian experiment demonstrates that a rat deprived of cerebral hemispheres, striatum, and thalamus still reacts to sudden noise with a sharp jump. This elementary motor response to auditory stimulation requires only the midbrain and more caudal parts of the central nervous system.

Vulpian Experiment, consists in the fact that a rat, deprived of the cerebral hemispheres, striatum, and thalamus, reacts to a sudden noise with a sharp jump. The elementary motor reaction to auditory stimulation thus requires, for its realization, only the preservation of the midbrain and more caudal parts of the central nervous system.
