Dr.Nissilä Finn said the device provides bright light stimuli both cranial bone, and blood of many vessels located in the temporo-parietal, resulting in activation of its antidepressant systems and stimulating the production of serotonin and endorphins.

Valkee researchers published their first results in “Medical Journal hypothesis”.
