Hello there,<br><br>I've been trying to analyze the data of a previous PPI experiment done in the lab I recently joined. A 64-channel EEG cap and bipolar VEOG and HEOG channels were used. The VEOG was recorded from supraorbital and suborbital sites and all recording was done using ANT's ASA system. The purpose of the experiment seems to have been to simply test startle reflex. (The EEG cap was also used in a second task after the PPI.) Would it be possible to use the VEOG channel in place of the usual EMG in measuring startle?<br>
<br>Thanks,<br>Sarah<br><br><br>
