The obvious and the more hidden components of the electroretinogram

If recorded in a precise and meticulous way the a-and b-waves of the ERG are very obvious deviations from the baseline, the standing potential of the eye. The c-wave, the oscillary potentials, the d- and the i-wave, and not to mention the photopic negative response, are considered more of the hidden ERG components in this publication. Elucidating these responses can be challenging but surely very exiting.
