Effect of field size on the colour evoked potentials and the electroretinogramWe have recorded colour evoked visual potentials (N87) and electroretino-grams (P60) with the stimulus diameter varied between 2° and 10°. VEPs tend to saturate at about 6°, while ERGs continue to increase in amplitude up to 10°. This different behavior is interpreted as a correlate of the cortical magnification of foveal vision.

NEEDY

A modified lantern testDisadvantages, variations and inaccuracies are found with existing lantern tests. Although neglected in some places, such methods are valuable. This account deals with some difficulties encountered and attempts to overcome them. A new choice of apertures and filters is described.
