An essential webinar for researchers interested in recording facial electromyography (fEMG) to measure muscle activity associated with facial expression, particularly smiling and frowning.

Facial EMG is a well-established technique with applications in the analysis and observation of speech, mastication and expression of emotion. Electrodes are used to detect the electrical impulses of two muscles in particular: the corrugator supercilii (used for frowning), and the zygomaticus (used for smiling).

In this training session, BIOPAC CEO Frazer Findlay demonstrates how fEMG with Smart Amplifiers can be used to track emotions and for a variety of other studies involving visual, auditory and haptic stimuli, startle response, emotional response, unconscious learning and more. Presented as a live demo, Frazer discusses optimal electrode placement and best practices for collecting fEMG signals from the zygomaticus and corrigator supercilii muscles.
