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.

Abstract: There is provided an arrangement, an accessory, an audio device, and at least one earpiece unit. The accessory is suitable for an audio device capable of providing an electrical audio signal. The accessory comprises first and second signal conveyers for conveying electrical audio signal driving audio transducers and electrical optic signal driving optical radiation sources, respectively. The audio transducers and the optical radiation sources are located in the earpiece unit.

Abstract: A portable electronic device comprises illuminating unit (300) configured to illuminate extrapupillarily the skin covering a user's eye cavity with optical radiation, thus resulting in diffuse propagation of optical radiation energy to an optically sensitive tissue of the user's eye, and adapting unit (500, 510, 520, 530, 550, 560) for adapting the illuminating unit (300) to the user's head.

Abstract: There is provided an apparatus, a method and a computer program. The apparatus comprises medical imaging unit for generating a group of voxel values of a patient, a voxel value representing an electromagnetically detectable functional state in a brain voxel of the patient, data processing unit for generating from the group of voxel values of the patient an indication that represents a level of a specific medical disorder of the patient, and illumination unit for directing non-invasively a dose of light to the brain of the patient.

Abstract: A method of light therapy includes non-invasive, intra-cranial administration of bright light via the ear canal of a subject by using a light intensity of 0.7-12 lumens, and a treatment time of 1-15 minutes. A medical device including radiation elements for directing the light via the ear canal for use in the light therapy is described.

Abstract: There is provided an arrangement, an accessory (200, 300), an audio device (202) and at least one earpiece unit (204A, 204B, 600, 700, 800). The accessory (200, 300) is suitable for an audio device (202) capable of providing an electrical audio signal. The accessory (200, 300) com-prises a first (208A, 208B) and a second (214, 214A, 214B) signal conveyers for conveying electrical audio signal driving audio transducers (206A, 206B) and electrical optic signal driving optical radiation sources (212A, 212B), respectively. The audio transducers (206A, 206B) and the optical radiation sources (212A, 212B) locate in the ear-piece unit (204A, 204B, 600, 700, 800).

Abstract: The present disclosure relates to a device and a method for non-invasively applying optical radiation to photosensitive parts of the brain. In particular the present invention is directed to a device for non-invasive/trans-cranial light therapy comprising one or more radiation units adapted to direct optical radiation at one or more neuroanatomical brain structures of a user from at least one extra-cranial position below the cerebrum of the user, said device applied for use in altering and/or controlling the production, release, re-uptake and/or metabolism of dopamine or serotonin in at least one of said one or more neuroanatomical brain structures and/or in the body of the user.

Abstract: A portable electronic ear light device comprising a support member and an optical radiation source resting on the support member and a light guide for directing optical radiation energy non-invasively at the user's intracranial nerve tissue via the outer auditory canal of the user of the portable electronic device to stimulate the user's intracranial nerve tissue. In the device, the support member is around the light guide at a distance from the radiation guide, thus providing an air gap around the radiation guide. In the device there is a sealing structure between the support member and the light guide for preventing the contamination of the light guide and the air gap.
