Bone conduction auditory brainstem response : ウィキペディア英語版 | Bone conduction auditory brainstem response Bone-conduction auditory brainstem response or BCABR is a type of auditory evoked response that records neural response from EEG with stimulus transmitted through bone conduction. ==Types of bone conduction==
Vibration of the skull results in auditory sensation. This is a way to somewhat bypass the outer and middle ears to stimulate the cochlea. Von Bekesy is credited with the discovery that at the level of the cochlea, phase shifted bone-conduction signals cancel out air conduction signals. Bone-conduction works because all of the bones of the skull are connected, including the temporal bone, which in turn stimulates the cochlea. Barany ''(1938)'' and Herzog & Krainz ''(1926)'' were some of the first researchers to examine the different components of bone-conduction hearing. Tonndorf ''(1968)'' found that there are three different forces that contribute to the forces needed to stimulate the cochlea: ''Distortional'', ''Inertial (Ossicular)'', and ''External canal (Osseotympanic)''〔Katz, J. (2002). Handbook of Clinical Audiology. Philadelphia. Lippincott Williams & Wilkins〕
