High frequency tone bursts of ultrasound are capable of suppressing and enhancing peripheral nerve action potential events. An in vitro frog sciatic nerve preparation was used as a biological model. The peak intensity of the sound delivered to the nerve was 150-200 W/cm2. Tone bursts consisted of 0.5 to 75 ms pulses delivered at a rate of 1-10 Hz and had center frequencies between 17 and 20 MHz.
