Acoustic startle electromyographic (EMG) Activity indexed from an electroculographic (EOG) Electrode placement: A methodological note

Abstract

Acoustic startle EMG responses were indexed from a traditional EOG electrode placement in 11 young adults while they viewed slides which varied in affective valence. We found, replicating earlier work that subjects' startle responses became more augmented as the content of the slides became more negative. The advantages of using an EOG electrode placement for measuring acoustic startle responses are discussed.
