Figure 6: The grimice produced is similar to a tic of the face 1854 - 1856

Guillaume Duchenne’s *Figure 6: The grimice produced is similar to a tic of the face* is a striking photographic study from his series *Electro-Physiologie Photographique*. The image captures the contorted face of a man, likely a patient, whose facial muscles have been stimulated with electrical currents to produce a specific expression. Duchenne, a neurologist, sought to understand the relationship between facial muscles and emotions through his photographic research, which pioneered the field of facial expression analysis. This work, now housed in the Metropolitan Museum of Art, remains influential in fields ranging from psychology to art.
