The scientific study of emotion began in the 19th century with Duchenne’s study of the “universal and immutable” language of facial expressions. In The Mechanism of Human Physiognomy, he manipulates human facial expressions by electrically stimulating facial muscles. Facial electromyography (EMG) is a modern technique that is reminiscent of Duchenne’s work; it allows researchers to measure facial muscle activity through surface recording electrodes, providing a real-time measure of natural emotional reactions.
Although facial EMG is a reliable measure of emotional behavior, it fails to provide any information about brain activity responsible for emotional processes. Functional magnetic resonance imaging (fMRI) …
