Recovery of contrast sensitivity during optic nerve regeneration in fish.
Psychophysical experiments on goldfish and sunfish studied the recovery time course of visual contrast detection during optic nerve regeneration. The results showed delayed recovery of detection of positive as compared to negative contrasts, and of high as compared to low spatial frequencies. The findings are related to previous electrophysiological and anatomical results in the fish retinotectal system.
