Changes in ultrastructure and electroretinogram of bullfrog retina during development.
A study has been made with the purpose of attempting to correlate the ultrastructural and electroretinographic changes in the retina of the bullfrog during embryonic growth. On day 8 afterExpand

A correlation of ultrastructure and function in the developing retina oof the frog tadpole.
The first electroretinographic response to light in developing tadpoles (Rana pipiens) was a purely cornea-negative slow potential which corresponded in time of first appearance with the firstExpand

A photosensitive pigment of the carp retina
Two visual pigments, rhodopsin (or visual purple) and porphyropsin (or visual violet) appear to have a widespread distribution. Thus Wald (1949), referring to rod pigments, writes: 'To summarize ourExpand

Delayed off-responses recorded from the isolated frog retina.
Using the isolated frog retina perfused with a glucose-containing physiological fluid, it is possible to demonstrate, by electrical recording, the presence of a delayed and slow off-potential, havingExpand
