Rabbits were raised in complete darkness for 7 months after birth. Eye movements were measured at the end of this period and in the next 3 months of normal light exposure with chronically implanted scleral coils. Horizontal optokinetic nystagmus (OKN) was tested inside a large drum which was rotated

Israelian gerbils (Meriones tristrami) reared in the dark from birth to 7-13 weeks of age show a clear optokinetic reflex in both horizontal directions under monocular viewing conditions. This is very different from gerbils reared in the light, which like many other mammals with lateral eyes show a
Kinetics of the development of orientation tuning are inferred from quantitative analysis of extracellular recordings in the primary visual cortex of normally and dark reared kittens. 712 visual cells were classified in three functional groups: a) non-specific cells, and b) immature cells which are
