Thank you for the post, which again shows the level of emotion that Valkee is creating.

Just one comment to correct the brain biology reviewed in this post:

* The University of Oulu team localized (no one had studied this before) the photosensitive OPN3 protein in the 18 areas of the human brain. Most of these areas are within the so-called oldest regions of the human brain, located directly behind the ear canal.

* Placing these areas (listed e.g. in the paper we published at the Scandinavian Physiology Society Annual Meeting 2011 available at http://www.valkee.com/uk/Valkee_Human_Photosensitive_Brain_OPN3_Bergen_2011.pdf) into the picture presented in this post (and the scientific poster at my earlier link) will reveal how directly the bright light via ear canal penetrates these areas. For exactly that reason it was included into the poster: for the brain scientist this picture tells more than thousand words.
