System and method for implantable neural sensing and stimulating probes

A method for neural simulation and control comprising:

• detecting neural signals from a medullary or spinal cord region of a patient using a CMOS electrode array comprising a plurality of semiconductor electrodes;
• digitizing the detected neural signals into binary outputs using a data processing unit, wherein the digitizing comprises generating a first binary value in response to detecting an action potential in the neural signals and generating a second binary value in response to an absence of the action potential;
• determining a physiological state based on the binary outputs;
• and
• generating stimulation signals to deliver to the medullary or spinal cord region through one or more of the plurality of semiconductor electrodes based on the determined physiological state.
