Behavioural Recovery from Visual Deprivation: Comments on the Critical Period

Part of the NATO Advanced Study Institutes Series book series (NSSA, volume 27)


Monocular deprivation imposed early in the life of kittens can have profound effects on the functional properties of neurons in the visual cortex (Wiesel and Hubel, 1963). These physiological consequences of deprivation have been described by other contributors to this volume, so we will not detail them here. Instead, we wish to concentrate on the behavioural consequences of monocular deprivation, and, in particular, upon the upper age limits of susceptibility to such deprivation. The experiments we shall describe form part of a series of studies of the visual critical period carried out in conjunction with Max Cynader at Dalhousie University.
