From vestibular implant to cortex: electrically evoked vestibular responses.

ABSTRACT:

Purpose

Understanding central vestibular pathways remains challenging and requires innovative measurement approaches. A vestibular implant offers unique access through specific electrical stimulation of the vestibular end organ. This study explored the feasibility of using vestibular implant stimulation to obtain vestibular evoked potentials, using electroencephalography (EEG).

Methods

A vestibular implant was used in nine participants to evoke vestibular potentials by targeting the ampullary nerves of the semicircular canals. Short latency potentials were recorded using one channel EEG on all participants. In three participants, long latency potentials were recorded with 128 channel EEG. Responses were analyzed in terms of latency, shape, and location, and tested for correl
