Reconfigurable multi-electrode apparatus

Abstract

Multi-electrode apparatuses and methods of using multi-electrode apparatuses are provided. The apparatuses each include a switching arrangement configured to selectively connect a group of one or more electrodes of the apparatus to a group of one or more circuits of the apparatus. Each electrode of the group may be selectively connected to multiple circuits each configured to provide a stimulation signal to the electrode concurrently, thus selectively increasing a range of amplitudes of an signal used to stimulate the electrode compared with a single circuit, and each configured to sense a signal from the electrode concurrently, thus permitting a signal-to-noise ratio (SNR) to be increased compared with a single circuit. The switching arrangement may be reconfigured to change a number of circuits connected to each electrode of the group, thus permitting the range to be further increased and the SNR to be further increased.
