Abstract
The portable electronic device includes radiation elements (104A, 104B) for directing optical radiation energy non-invasively at intracranial nerve tissue of a user through an external auditory canal of the user of the portable electronic device to stimulate the user's intracranial nerve tissue. Stimulation may have a metabolic and/or nervous response, which appears as a change in alertness, diurnal rhythm and in concentrations of several hormones and brain transmitters.
