| Outline of Final Research Achievements |
We investigated the light response properties in human and mouse. In light adapted mouse, polychromatic light increases the response of neurons in suprachiasmatic nucleus more than monochromatic light. In contrast to mouse, such beneficial effect of polychromatic light could not be detected. We could identify the wave form which can reflect the intrinsic light response of retinal ganglion cell setting circadian rhythm in mouse.
