Basilar membrane vibration in the gerbil hemicochlea.
Excised gerbil cochleae were cut along the mid-modiolar plane (hemicochlea). Along one-half turn of this preparation, fluorescent microbeads were placed on the basilar membrane (BM). The BM was vibrated with click stimuli (50 micros) produced mechanically by a piezo pusher. The stimulus delivery probe could be positioned either more apical or more basal from the beads. Vibration patterns were m...

متن کاملCochlea of the dolphin, Tursiops truncatus: the basilar membrane.
In the dolphin Tursiops truncatus, the basilar membrane over its course its course from basal to apical ends shows a systematic variation in width and in the manner and rigidity of its suspension. The suspension is by bony laminae on both the outer and inner edges in the basal region, and by progressively less rigid attachments in the more apical regions, until near the apex the membrane is hel...
متن کاملBasilar membrane resonance in the cochlea of the mustached bat.
The mustached bat (Pteronotus parnellii) detects the wing beats of prey insects by resolving small frequency modulations in the return echoes to the constant frequency component of its echolocation call at about 61 kHz. The fine frequency discrimination required for this task is due largely to the mechanical properties of the cochlea, as indicated indirectly by the presence of large otoacoustic...
متن کاملRound Window Membrane and Delivery of Biologically Active Agents into the Cochlea
Establishing efficient methods for local administration of drugs to the inner ear has great clinical relevance for the management of inner ear disorders. However, the administration route remains a critical issue. The most feasible approach for a non invasive drug delivery to the inner ear is application of medication to the middle ear cavity on the promise that it will diffuse through the thin...
