Abstract: The neuromodulation system can include a headpiece comprising. The headpiece can include a first surface, a second surface opposite the first surface, and a plurality of electrodes coupled to the first surface of the headpiece, each of the plurality of electrodes can have a known spatial relationship to each other. The neuromodulation system can include at least one placement marker coupled to the second surface. The at least one placement marker can have a known spatial relationship to each of the plurality of electrodes in order to facilitate correct positioning of the headpiece relative to an anatomical feature of a user. The neuromodulation system can include an electrical signal generator in communication with the plurality of electrodes, and a controller device in communication with the electrical signal generator and configured to operate the electrical signal generator in order to generate an electrical stimulation using the plurality of electrodes.
