Abstract

A photobiomodulation device may include a housing configured to be inserted into an external auditory meatus of a human ear, at least a one irradiation source coupled to the housing such that at least a portion of a radiation emitting surface thereof faces at least a portion of dermis of the external auditory meatus of the ear beneath which at least one of an arterial branch and a peripheral nerve branch of at least one cranial nerve is located, and an electrical circuit carried by the housing and configured to control the at least one radiation source to irradiate the at least one of the arterial branch and the peripheral nerve branch of the at least one cranial nerve through the at least a portion of dermis of the external auditory meatus of the ear.
