A Programmable Neural Interface for Investigating Arbitrary Stimulation Strategies
نویسندگان
چکیده
This paper presents a microcontroller-based neural interface capable of producing arbitrary current-mode waveforms for use in developing and evaluating electrical stimulation strategies. The presented application-specific customisation focuses on charge-balanced biphasic waveforms delivered to a bipolar electrode configuration, although the hardware is capable of interfacing with other electrode topologies and/or producing different waveform profiles. The system comprises of a MATLAB-based GUI for specifying the stimulus profiles and delivery parameters, a USB link to transfer the data between the PC and embedded controller, and the stimulator hardware, which, once programmed can operate as a portable battery-powered module.
