alternating checkerboard stimulus

0.01 sec.

A type of light stimulus used in performing electrophysiological testing. Most often used in the pattern electroretinogram (pERG), it maintains constant luminance to the entire retina. The pERG measures ganglion cell function, in contrast to the ERG, which measures the function of the photoreceptor and bipolar cell layers of the retina.
