Abstract:
Parts of the left tecta of the frogs were removed in one group. In another group, the left optic nerves of the frogs were cut through the mouth. The first group of animals survived for 12~26days and the second group 11~22 days. Both right and left retinas (with a small piece of optic nerve attached) were sectioned radially at 25?m on a freezing microtome and stained by Ebbesson-Heimer's method which allow degenerating fibers and terminals stained specially. We did not find any evidences showing degeneration. We concluded that centrifugal fibers coming from the centers to the retinas were absent in the frog.
