Human Brain Is Sensitive To Light In Ears

Posted by timothy on Thursday August 11, 2011 @09:19AM from the also-to-the-name-of-the-devil dept.

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."

Oh god, reading that press release it just gets better.
They reckon that because a photosensitive protein is found in the human brain, shining light in through the ears must help in seasonal affective disorder. To demonstrate this they cut up some cadavers and showed that this protein was found in their brain.
I'm quite certain you can't see the brain by looking in through the ear canal.
