Optimizing Neural Stimulation: Tight Contact Spacing Computational Model

Explore benefits of tight contact spacing in neural stimulation, essential for avoiding gaps. Learn about nerve potential mapping, depolarization, hyperpolarization, and neuron firing thresholds. This model, based on Rattay's work, illustrates the importance of contact distance. Dive into the implications of tight vs. wide contact spacing and the continuous vs. discontinuous models. Discover how strategic spacing impacts neural activation. Join us for insights into improving neural stimulation methodologies.
