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(More)
Impulse activity of the ischiatic nerves single fibres in response to focused ultrasound stimulation of the rat hind-foot receptive fields, was studied. The receptor units were divided into low-, average- and high-threshold groups by the value of their threshold responses. No impulse activity was revealed in response to direct action of cold or warm water(More)
