![Page 1: The Scotopic ERG Response A dim flash of light below the sensitivity threshold for cone photoreceptors stimulates only the rods in a dark adapted eye.](https://reader036.fdocuments.in/reader036/viewer/2022062620/551b3dfd550346ae7a8b489b/html5/thumbnails/1.jpg)
The Scotopic ERG ResponseA dim flash of light below the sensitivity threshold for cone photoreceptors stimulates only the rods in a dark adapted eye. An electrode placed on the cornea records the changing electrical potentials of the cells in the retina.http://www.iscev.org/standards/index.html

The Scotopic ERG ResponseA flash of light stimulates both rod and cone photoreceptorsin a dark adapted eye. An electrode placed on the cornea records the changing electrical potentials of the cells in the retina.http://www.iscev.org/standards/index.html

Multifocal electroretinogram (mfERG):
http://www.webvision.utah.edu
records focal responses from several locations in
retina simultaneously primarily tests middle and outer retinal layers
