EVestG signals: Feature selection

A vertical movement stimulus has been applied to 10 healthy subjects in the prone position and recordings of the vestibular responses made using an EVestG configuration. The response encoding has been examined using a novel Neural Event Extraction Routine (NEER) developed to detect otoacoustic field potentials. The potential measures 1. average field potential amplitude and 2. average number of field potentials detected per stimulus phase are examined for suitability as vestibular dynamic performance indices. Average field potential amplitude change produces the larger percentage change during vertical acceleration phases.
