| Research Abstract |
The frequency characteristics of non-visual photoreceptor; melanopsin expressing retinal ganglion cells (mRGCs) were investigated with the light which stimulates mRGCs independently. The results showed the mRGCs response to a light stimulus at around 8Hz was high. In contrast, th e response to light stimulus tended to be smaller under light condition that change at lower and higher frequencies. The effects of blue LED light on melatonin secretion were investigated under the v arious frequencies. The melatonin secretion was not inhibited by the blue LED light with frequency changes at 1000Hz and 7.14Hz, although it was inhibited by the constant blue LED light at nighttime.
