Sensory transduction and frequency selectivity in the basal turn of the guinea-pig cochlea.
Receptor potentials recorded from outer hair cells (OHC) and inner hair cells (IHC) in the basal high-frequency turn were compared. The DC component of the IHC receptor potential is maximized to ensure that IHCS can signal a voltage response to high-frequency tones. The OHC DC component is minimized so that OHCS transduce in the most sensitive region of their operating range. The phase and magn...
متن کاملArterial supply of the guinea pig mandible.
It has been shown that the blood supply of the coronoid process, mandibular angle, and condyle of the rat, monkey, and man arises from arteries that supply the muscles attaching to these processes, and generally not from the inferior alveolar artery which primarily supplies the mandibular body and teeth.'-5 It is the purpose of this study to demonstrate the intraosseous blood supply of the guin...
متن کاملAcute perilymphatic perfusion of the guinea pig cochlea.
A method for the continuous perfusion of the perilymphatic space of the inner ear in the guinea pig is described. Artificial perilymph is supplied to the cochlea and drained away through a tubing system while flow rates from 10 microliters/min to 0.3 ml/min are established by gravity syphon pressure. Techniques are also presented which allow control over the temperature of the perfusate and ov...
متن کاملVelocity of red blood cell flow in capillaries of the guinea pig cochlea.
Velocities of red blood cells (RBCs) in the lateral wall of the cochlea were determined in the anesthetized guinea pig from direct optical microscopic observations. Mean flow velocity of the blood was measured by timing the passage of a fluorescently-labeled subpopulation of RBCs across a measured capillary length. The optical observations were achieved using an intravital microscope equipped f...
متن کاملImmunocytochemical localization of glutamate immunoreactivity in the guinea pig cochlea.
The localization of glutamate immunoreactivity was examined in the guinea pig cochlea using affinity purified polyclonal antibodies to glutamate and immunoperoxidase post-embedding staining techniques on one micron plastic sections. Glutamate immunoreactive staining was seen in both inner and outer hair cells and in spiral ganglion cells and auditory nerve fibers. These results support the hypo...
