Abstract :
Electrovestibulography (EVestG) is a new diagnostic technique potentially applicable to detecting neurological changes impacting on sensory performance. A complex Morlet wavelet based signal processing technique, a neural event extraction routine, has been used to extract diagnostically meaningful biomarkers from these EVestG recordings. Separation of Meniere\´s disease and benign paroxysmal positional vertigo (BPPV) has been accomplished using a "DC" biomarker. When using tilt stimuli to evoke a semi circular canal response, otolithic organ responses are also observed. The origin of this "DC" biomarker is likely a multifaceted dipole generated by both semi circular canal and otolithic structures.
