235 – Zygomaticus Measures with Pressure Pad vs. EMG in MRI or fMRI

This application note is concerned with the recording of Zygomaticus measures using a pressure pad transducer vs. EMG electrodes during MRI or fMRI investigations. With some MRI protocols, especially those with extensive and rapid gradient switching cycles, it has proven helpful to employ indirect methods of recording facial EMG activity to better isolate periods of activity. BIOPAC has successfully employed a pressure pad transducer to record minute changes in muscle contraction simultaneously with EMG, such as on the Zygomaticus, to obtain a measure of smiling.
