Patent ID: 8874220

Claim:
A device for cranial nerve stimulation of an individual, the device comprising: a signal driver unit for providing both AC and DC current; an intraoral stimulation board having at least one primary electrode for the AC current and at least one primary electrode for the DC current, the respective primary electrodes being configured for communicating the respective currents with the tongue of the individual, the intraoral stimulation board connected to the signal driver unit; at least one secondary electrode configured to be positioned on the cranium of the individual for communicating either the AC or DC current through the brain of the individual, the at least one secondary electrode connected to the signal driver unit, wherein either the AC or DC current can flow between the intraoral stimulation board and the at least one secondary electrode to apply transcranial current stimulation; and a partial conductive cover that covers part of the intraoral stimulation board for preventing deposition of electrode materials onto the tongue when direct current is applied, wherein the AC current is provided by the at least one primary electrode that is uncovered, and the DC current is communicated by the at least one primary electrode that is covered, and wherein the AC current and DC current are communicated simultaneously.
