Human Brain Is Sensitive To Light In Ears 130

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."
