| Outline of Final Research Achievements |
Toward the future iPS cell therapies, we study about an objective monitoring scheme of retinal functions via analyses of the mfERG using mathematical models of the retina. As a preliminary study, we examined spatial sensitivities of the carp retina by using mfERG. MfERG results showed that the spatial distributions of retinal light responses in carp showed regional differences. Compared to the large response in the ventral-temporal retina region, small responses were found in the dorsal-nasal region and optic nerve located in the center of the retina. This result was in agreement with the high density of retinal ganglion cells in the ventral-temporal region of cyprinid zebrafish (Mangrum et al. 2002; Pita et al. 2015). The result in this report is an important evidence for our purpose.
