Source analysis of short and long latency vestibular-evoked potentials (VsEPs) produced by left vs. right ear air-conducted 500 Hz tone pips.

Todd NP, Paillard AC, Kluk K, Whittle E, Colebatch JG - Hear. Res. (2014)

Bottom Line: Statistical analysis of the vestibular dependent responses indicated a contralateral effect for inion related short-latency responses and a left-ear/right-hemisphere advantage for the long-latency responses.In addition we found evidence of a possible vestibular contribution to the auditory T-complex in radial temporal lobe sources.These last results raise the possibility that acoustic activation of the otolith organs could potentially contribute to auditory processing.

Grand means of evoked potentials produced by 500 Hz, 2 ms pips from left ear stimulation in 10 healthy subjects. For each electrode location the two traces show the supra-threshold (maximal intensity) vs. sub-threshold (−12 dB re VT) conditions as black and grey traces respectively. All electrodes are referred to the auricle leads.
