Afferent innervation patterns of the pigeon horizontal crista ampullaris.
The vestibular semicircular canals are responsible for detection of rotational head motion although the precise mechanisms underlying the transduction and encoding of movement information are still under study. In the present investigation, we utilized neural tracers and immunohistochemistry to quantitatively examine the topology and afferent innervation patterns of the horizontal semicircular ...
متن کاملHair cell tufts and afferent innervation of the bullfrog crista ampullaris.
Within the bullfrog semicircular canal crista, hair cell tuft types were defined and mapped with the aid of scanning electron microscopy. Intracellular recording and Lucifer Yellow labeling techniques were used to study afferent responses and arborization patterns. Dye-filled planar afferent axons had mean distal axonal diameters of 1.6-4.9 microns, highly branched arbors, and contacted 11-24 h...
متن کاملEffect of parenteral aminoglycoside administration on dark cells in the crista ampullaris.
OBJECTIVE To observe the early and late effects of the parenteral administration of aminoglycosides on the dark cells of ampullae in the inner ear. STUDY DESIGN Comparative study of the histopathologic characteristic of human temporal bones. SUBJECTS AND METHODS Sixty-three temporal bones from 44 subjects (age range, 16-81 years) were examined by light microscopy. Three groups of temporal b...
متن کاملCalcium currents in solitary hair cells isolated from frog crista ampullaris.
Some properties of Ca2+ currents in hair cells isolated from frog semicircular canals by enzymatic or mechanical treatment were studied by using the whole-cell configuration of the patch-clamp technique. After blocking the large outward K+ currents by substituting Cs+ for K+ and adding tetraethylammonium to the pipette filling solution, voltage- and time-dependent inward currents were clearly d...
متن کاملCharacteristics of gentamicin uptake in the isolated crista ampullaris of the inner ear of the guinea pig.
The characteristics of aminoglycoside uptake in the inner ear were investigated in the isolated crista ampullaris. The organ was incubated with radiolabeled gentamicin, and the stable, nonexchangeable radioactivity was considered the intracellular pool of the drug. Gentamicin was transported against a concentration gradient, and the resulting tissue to medium ratios ranged from 1.4 to 18.6. Tra...
