Abstract/OtherAbstract:
|
1. A standing wave tube apparatus was used to determine the biophysical basis of underwater hearing in Ambystoma tigrinum. 2. A. tigrinum responds to the pressure component of underwater sound, and the mouth cavity appears responsible for transduction of sound pressure. 3. Near-field displacements produced by pulsations of the air-filled mouth cavity apparently stimulate the inner ear. 4. Salamander head preparations with no air-filled mouth cavity respond to the particle motion component of underwater sound, but only at sound pressure levels 40 dB or more above levels producing clear pressure sensitivity in intact salamanders or head preparations including an air-filled mouth cavity. |
