The effect of dark rearing on the time course of the critical period in cat visual cortex

Mower, George D.·1991·Developmental Brain Research

Abstract

The effects of dark rearing on the time course of the postnatal critical period for monocular deprivation (MD) in visual cortex were determined in cats who experienced 2 days of MD at various postnatal ages. In normal development, plasticity (susceptibility to MD) was very low at 3 weeks, rose sharply at 6 weeks, and gradually declined over the next 10 weeks. This developmental profile was dramatically altered by dark rearing which slowed the entire time course of the critical period. In dark reared cats, plasticity rose steadily over the first 12 weeks, and was maintained at 16 weeks. There was a crossover of the two profiles of the critical period such that at young ages (6 weeks) normal cats were more plastic than dark reared cats while at later ages (after 9 weeks) dark reared cats were more plastic. A second experiment indicated that dark rearing slowed down the progression of the critical period even after it had been initiated by a period of normal vision. MD produced substantial effects after the normal critical period in cats who were reared normally for the first 6-8 weeks of life and then placed in darkness until 5 months of age. The results are discussed in terms of a simple model of the accelerating effect of visual input and the decelerating effect of total darkness on the time course of the critical period.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
