TRANSCRIPT
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):

records focal responses from several locations in
retina simultaneously primarily tests middle and outer retinal layers
