1. A method to control spatial positioning of a prosthetic device, the prosthetic device able to assume multiple spatial positions upon input from a subject, the method comprising:

  • recording eye position information of the subject to produce an eye position signal, the eye position information including a portion recorded during a scan stage that occurs after the subject views a plurality of reach goals but before the subject selects one of the plurality of reach goals;

    recording neural activity of the subject to produce a neural activity signal, the neural activity including a portion recorded during the scan stage;

    combining the eye position signal and the neural activity signal to provide a recorded behavioral pattern;

    comparing the recorded behavioral pattern with at least one predetermined behavioral pattern to identify a matching predetermined behavioral pattern associated with a selection of one of the plurality of reach goals and at least one predetermined spatial position of the prosthetic device; and

    positioning the prosthetic device in the spatial position associated with the matching predetermined behavioral pattern.
