Abstract:
The photopic negative response(PhNR)from photopie electroretinogram(ERG)is a slowly negative potential following positive b wave.The experimental study of primates and clinieal observation of patients determined that PhNR arise from retinal ganglion cells(RGCs)and their axons.But the research result of rodents suggested that PhNR of mice and rats,unlike in human and primates,originate from amaerine cells.Recently,the study progress in PhNR is eoncemed by more and more researchers.The study of PhNR in the focal ERG,the influence of different recording conditions on PhNR wave and the character as well as recording condition of PhNR wave in rodents were introduced in this paper.
