This research project will study quantitatively the response elicited by a stimulating electrode on a representative nerve trunk. The model will include fiber caliber and distribution through the nerve trunk. The goal is to achieve selective activation of only the target neurons (either sensory or motor) with currents which are low enough to avoid unacceptable electro-chemical processes at the electrodes. Little is presently known about how current from point or cuff electrodes distribute to individual neurons in a nerve bundle. This information is important in the design of electrodes for neural prostheses - an area of great important to neurologically handicapped people.

本研究项目将定量研究引起的反应 通过在代表性神经干上的刺激电极。 模型 包括神经纤维的口径和分布 其目标是实现仅靶神经元的选择性激活 （感觉或运动）电流足够低，以避免 在电极处的不可接受的电化学过程。 之甚少 目前已知来自点电极或袖带电极的电流 分布到神经束中的单个神经元。 这些信息 在神经假体的电极设计中很重要- 对神经残疾人来说非常重要的领域。
