INDIVIDUALLY CONTROLLED, DUAL-ROLE MICRO-ELECTRODES

Systems and methods are disclosed for a neural interface. In one implementation, a neural interface comprises a neural probe configured for placement within a brain; at least one signal lead extending from the neural probe; and a sensing assembly included on the neural probe, where the sensing assembly includes: a plurality of dual-role electrodes positioned on the neural probe, wherein each of the dual-role electrodes is configured to sense electrical signals generated by one or more neurons in the brain and to convey to the at least one signal lead one or more sense signals generated based on the sensed electrical signals, and wherein each of the dual-role electrodes is configured to receive, via the at least one signal lead, a stimulation signal selectively delivered from a stimulus generator.
