vuo writes "Finnish researchers have shown that the human brain contains photoreceptors that react to intracranial illumination. Light is provided through the ear canal with bright-light headsets by Valkee. These devices, much like earphones or should we say 'earlumes,' are registered medical devices. Retinal illumination or bright-light therapy has been previously assumed to be the only way light indirectly affects brains. Light therapy helps with mood swings, seasonal affective disorder, jetlag and other circadian rhythm disruptions."
