The Effect of Light on the Appearance and Development of the Electroretinogram in Newborn Kittens

Abstract

Summary. In order to determine the effect of light on the development of the ERG, this response has been recorded in kittens bred in darkness and in kittens bred in daylight. The appearance of an ERG in kittens bred in darkness in the majority of cases was found to be considerably delayed. The latent period of the b‐wave of the ERG in animals bred in darkness was likewise prolonged in comparison with those bred in light. The significance of these results has been discussed.
