Abstract: Biocompatible electrodes with smaller geometric area improve the selectivity of the neural recording and stimulation applications. A volume within the electrode back plane of a micro-reaction chamber (?RC) is used to confine and sequester an electrochemical reaction used for charge passage. The ?RC electrode decreases impedance and improves charge storage capacity without altering the geometry of the active site.

Abstract: A DC electric field is applied to brain tissue in parallel alignment with urons thereof during periods of brief duration while the tissue is undergoing epileptic activity. The electric field is controllably changed in polarity and magnitude to modify such epileptic activity based on data obtained by recording such activity through electrodes that are isopotentially aligned within the electric field imposed on a slice of the brain tissue.
