Facial EMG & Startle Response

BIOPAC fEMG electrodesFacial electromyography (fEMG) typically uses surface EMG electrodes to detect activity at the zygomaticus (cheek), orbicularis oculi (under eye), and/or corrugator supercilii (brow) muscle regions as a participant is exposed to a stimulus, such as sounds, pictures, or smells for psychophysiology or neuroscience studies.

Multiple stimulus paradigms for Startle Response applications can be set. Present a pre-defined auditory stimulus or stimulate the subject based on the result of a physiological response. Turn on lights or generate tones for detailed reaction time studies. Deliver auditory stimuli for startle response paradigms.

To perform multiple stimulus paradigms for Startle Response applications, use the STM100C stimulator and the MP System Control channels. Present a pre-defined auditory stimulus or stimulate the subject based on the result of a physiological response. Turn on lights or generate tones for detailed reaction time studies. Auditory stimuli can also be used to deliver auditory stimuli for startle response paradigms.

This is one of many ADVANCED FEATURES for the selected Application. Scroll down for hardware options.

The eye blink response is captured after the sound is delivered to the subject. Use a wired or wireless EMG amplifier and surface EMG electrodes to record facial EMG (eyeblinks); for MRI protocols, record zygomaticus activity with an MR Safe pressure pad transducer (see TSD110-MRI and Application Note 235). Set the software to integrate the signal on-line. Calculate the time and amplitude of the response using the measurement tools. Automate analysis with the Peak Detection features and display the results as a new channel.

Alternatively, the auditory stimuli can be delivered from a presentation system such as E-Prime or SuperLab and the automated stimulus analysis software can be used to calculate the latency and amplitude of the response. AcqKnowledge will convert the trigger marks from the presentation system into software events and then AcqKnowledge will use the events as part of the Stim-Response Analysis routine. AcqKnowledge can also interface with third-party stimulators including transcranial magnetic stimulation. The software also interfaces with the major presentation systems for the delivery and timing of the stimulus delivery.
