Francesco Duchenne

Francesco Duchenne was a 19th-century Italian neurologist best known for his research on muscle disorders and facial expressions. He studied conditions like muscular dystrophy and contributed to understanding how muscles work and deteriorate. Duchenne developed techniques to analyze facial movements, helping to identify genuine emotions based on muscle activity, a method still used today in psychology and lie detection. His work laid important foundations for neurology and the study of neuromuscular diseases.
