Electromyography (EMG) showed lower compound muscle action potential (CMAP) amplitude on the left facial nerve compared with the right side (facial nerve CMAP amplitude recording on musculus nasalis was 1.8 mV on the right and 0.7 mV on the left; facial nerve CMAP amplitude recording on musculus orbicularis oculi was 1.1 mV on the right and 0.2 mV on the left).
Those people who can do so use a muscle called the musculus nasalis.
