  • System and method for selective neural activation using high-frequency electrical stimulation
    Patent number: 9737711
    Abstract: A system and method is provided for preferentially stimulating a portion of neural tissue including a first type of neurons and a second type of neurons. The method includes defining a waveform characterizing an electrical stimulus, wherein the waveform includes an amplitude-modulated wave of the electric stimulus. The method also includes applying the electrical stimulus having the defined waveform to a stimulating element located in proximity to the neural tissue to selectively activate the first type of neurons while leaving the second type of neurons one of substantially unaffected and suppressed in response to the electrical stimulus.
