Modeling the Impact of Surrounding Dielectric Width on the Range and Shape of the Recording Volume of Disc Microelectrodes

Efforts to reduce the size of implanted microelectrodes and their supporting dielectric material are being driven by demands to reduce the foreign-body tissue response and increase spatial resolution. Although the impact on recording performance of electrode size and shape have been analyzed in both prior and on-going work, the impact of the width of the surrounding dielectric has not. In this wor...
