...Allen F. Mensinger; Jacey C. Van Wert; Loranzie S. Rogers ABSTRACT A longstanding question in aquatic animal sensory physiology is the impact of self-generated movement on lateral line sensitivity. One hypothesis is that efferent modulation of the sensory hair cells cancels self-generated noise...

...Allison Campbell; Ashlyn Dykes; Patricia Mire ABSTRACT Animals employ hair bundles on hair cells to detect flow, vibrations and gravity. Hair bundles on sea anemone tentacles detect nearby vibrations in the water column produced by prey movements and then regulate discharge of cnidae to capture...

... schooling behavior, no one has examined how the behavior recovers as the sensory system regenerates. We studied how schooling behavior changes in giant danios, Devario aequipinnatus , when their lateral line system is chemically ablated and after the sensory hair cells regenerate. We found that fish could...

...Kevin N. Rohmann; Joel A. Tripp; Rachel M. Genova; Andrew H. Bass Non-mammalian vertebrates rely on electrical resonance for frequency tuning in auditory hair cells. A key component of the resonance exhibited by these cells is an outward calcium-activated potassium current that flows through large...

... auditory afferents. In this study, evoked potentials were recorded in vivo from the saccule, the main auditory division of the inner ear of most teleosts, to test the hypothesis that males and females exhibit seasonal changes in hair cell physiology in relation to seasonal changes in plasma levels...

...Dominik Oliver; Martin Brinkmann; Thiemo Sieger; Ulrich Thurm SUMMARY Nematocytes, the stinging cells of Hydrozoa, can be considered as prototypic mechanosensory hair cells bearing a concentric hair bundle, the cnidocil apparatus. These cells produce typical mechanoreceptor potentials in response...

...William M. Roberts; Mark A. Rutherford SUMMARY Mechanosensory hair cells in the ear are exquisitely responsive to minute sensory inputs, nearly to the point of instability. Active mechanisms bias the transduction apparatus and subsequent electrical amplification away from saturation in either...

...Michael E. Smith; Allison B. Coffin; Diane L. Miller; Arthur N. Popper SUMMARY Fishes can regenerate lateral line and inner ear sensory hair cells that have been lost following exposure to ototoxic antibiotics. However,regenerative capabilities following noise exposure have not been explored...

...J. M. Lovell; R. M. Moate; L. Christiansen; M. M. Findlay SUMMARY The organisation of the statocyst hair cells and auditory evoked potentials(AEPs) generated by the afferents in three body size classes of prawn( Palaemon serratus ) have been studied using a combination of anatomical, electron...

... been suggested( Coombs et al., 1996 ) that the lateral line system, with its two morphological populations of directionally sensitive hair cells, is ideally equipped for such a task. The largest distance between two phase reversals in an array of lateral line detectors is limited to its overall length...

... skin depression velocity was 2–10 times greater than to hydrodynamic dipole stimulation near the skin. No morphological specialization of hair cell orientation was found among pored and non-pored canals. These low frequency, tactile response properties support the hypothesis that the stingray's non...

The mechano-sensitive hair cell, as the focal point of transduction, figures critically in the encoding of acoustic information...

...Bernd U. Budelmann; Roddy Williamson ABSTRACT Changes in threshold sensitivity of hair cell afferents of the macula and crista of the Octopus statocyst were analyzed when the hair cells were stimulated with sinusoidal water movements from different directions. The experiments indicate...

...S. A. Arkett; G. O. Mackie; R. W. Meech ABSTRACT The jellyfish Aglantha digitale is equipped with clusters of hair cells on the velum and on the tentacle bases. The cells have a central non-motile cilium surrounded by a collar of microvilli. The microvilli are graded in length, from long on one...
