Transcranial bright light - The effect on human psychophysiology

" ... Altogether, TBL [transcranial bright light] seems to affect human brain function by alleviating symptoms of jet lag and SAD [seasonal affective disorder] and improving psychomotor performance. The acute effect is suggested to be mediated via structures unrelated to acute melatonin secretion i.e. the retinohypotalamic tract (RHT). These results support the light sensitivity of the human brain although the mechanism of action is not yet established.
