Electrical microstimulation is an invaluable tool in neuroscience research to dissect neural circuits, relate brain areas, and identify relationships between brain structure and behavior. In the clinic, electrical microstimulation has enabled partial restoration of vision, movement, sensation and autonomic functions. Recently, novel materials and new fabrication techniques of traditional metals have emerged such as iridium oxide and the conducting polymer PEDOT/CNT. These materials have demonstrated particular promise in the improvement in electrical efficiency. However, the in vivo stimulation efficiency and the in vivo stability of these materials have not been thoroughly characterized. In this dissertation, we use a multimodal approach to study the efficiency and stability of electrode-tissue interface using novel materials in microstimulation.
