A device may include an implantable circuit and at least one pair of implantable electrodes, in electrical communication with the implantable circuit. The circuit and the electrodes may configured for implantation in a subject in the vicinity of a nerve. The circuit may be configured to deliver to the electrodes an electrical signal having a current less than about 1.6 milliamps, and the electrodes may be configured to emit an electric field such that a portion of the field lines extend along a length of the nerve such that the delivery of the electrical signal of less than about 1.6 milliamps causes modulation of the nerve.
