Development in the Visual Cortex

Synopsis
Presents the results of Dr Colin Blakemore’s 1970s’ research on plasticity of neuronal responses in the visual cortex. Describes the concept of a ‘sensitive period’ in visual development by reference to Hubel and Wiesel’s work on monocular deprivation: the effect of reversal of this procedure. Dr Blakemore shows, in cats, both behavioural and neurophysiological evidence for there being a particularly critical period of about 28 days when the visual input determines the subsequent capabilities of the animal’s visual system. The works is shown to have a place in the wider context of cortical development and adaptation to experience.
