title: [Stimulating effect of focused ultrasound on auditory fibers of the acoustic nerve in the frog Rana temporaria].
abstract: After mechanical destruction of the receptor apparatus, application of focused ultrasound (frequency 2.34 mHz) to the auditory fibers of the frog elicited the electrical activity in the auditory midbrain centers (torus semicircularis). Action potentials evoked by focused ultrasound were similar to those evoked by activation of the intact contralateral labyrinth. After introduction of horseradish peroxidase into the destroyed auditory capsule, fibers activated by ultrasound were detected. Therefore electrophysiological and histochemical experiments reveal stimulating effect of focused ultrasound on the auditory fibers of the VIIIth nerve.
