【Abstract】 Objective To investigate the expression of c-fos in the superior colliculus after flash stimulation to the transplanted retina, and to test the responses of transplanted retina to flash stimulation. Method The rats were divided into two groups:the flash stimulated group and the normal group, and the c-fos immunohistochemical method was used.Result Clear expression of c-fos appeared in the superior colliculus after 1h’s flash stimulation on both the transplanted retina and the normal retina, and peaked 2～3 hs later. Conclusion The flash stimulus can evoke c-fos expression in the superior colliculus of the rats with transplanted retina. It indicates that the transplanted retina can react to the flash stimulation.更多还原
