the scotopic erg response
DESCRIPTION
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. An electrode placed on the cornea records the changing electrical potentials of the cells in the retina. - PowerPoint PPT PresentationTRANSCRIPT
