Vanderbilt Audiology Journal Club: Vestibular Update - The Inion Potential

---

1.  Which of the following is not a short latency evoked response? P1 of the cVEMP R1 of the blink reflex Pa component from the MLR N1-P2 of the late cortical response

2.  According to Todd et al., the p10 component of the p10-n17 response recorded from the posterior occipital electrodes was likely cerebellar because of what effect of gaze? Largest amplitude in neutral gaze suggesting increased cerebellar inhibition. Largest amplitude in upward gaze like oVEMP response. Largest amplitude with downward gaze because the electrode is closer to the generator source. There was no effect of gaze on this component of the response.

3.  According to Todd et al., portions of their responses, like the inion response,were modulated by head position because of what? Cerebellar influence Extraocular muscle influence Inferior oblique influence Cervical muscle influence

4.  The vestibular cerebellar evoked potential uses what type of stimulus? Click 500 Hz tone burst Tone pip Jerk stimulus

5.  Based on data presented, the VsCEP is best recorded (defined as largest amplitude and highest response rate): Ipsilateral to the stimulated ear Ipsilateral and contralateral to the stimulated ear Midline and contralateral to the stimulated ear At midline only
