웹Kathryn Hopkins, in Handbook of Clinical Neurology, 2015. Outer hair cells. Outer hair cells amplify basilar membrane motion (Ashmore, 1987).The amount of amplification is greatest at low input levels and at frequencies close to the characteristic frequency of the place on the basilar membrane where the hair cell is located (Rhode, 1971; Sellick et al., 1982). 웹2014년 6월 23일 · In a hypothetical symmetric inner ear, in which the areas are equal, deformation of the cochlear bone would not elicit basilar-membrane waves, as had already been remarked by Békésy 24. screening osteoporosis guidelines웹What is basilar membrane in psychology? a fibrous membrane within the cochlea that supports the organ of Corti. In response to sound, the basilar membrane vibrates; this leads to stimulation of the hair cells—the auditory receptors within the organ of Corti. This fundamental aspect of mammalian hearing was discovered by Georg von Békésy . …. screening out police

"웹The oscillations of the basilar membrane deflect hair bundles, the mechanically sensitive organelles of the ear's sensory receptors, the hair cells. As mechanically sensitive ion channels open and close, each hair cell responds with an electrical signal that is chemically transmitted to an afferent nerve fiber and thence into the brain.
