title: Electrovestibulography: the "DC" potential used to separate Meniere's disease and Benign Paroxysmal Positional Vertigo.
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 [1]. 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.
