Neurostimulation Techniques
This lecture covers constant-voltage and constant-current stimulation techniques used in neurostimulation. It explains how constant-voltage pulses are generated, the limitations of controlling current due to impedance variations, and the safety issues involved. Additionally, it discusses the implementation of constant-voltage and constant-current stimulation circuits, the concept of charge-controlled stimulation, and the maximal safe level of stimulation. The lecture also delves into electrode analysis, biphasic charge-balanced stimulation, and typical waveforms used in current-controlled stimulation.
