Introduction The vision of newborn infants is crude. As infants experience the normal visual environment, their vision rapidly improves, with different visual capabilities emerging at different ages. Determining the exact…
Introduction “No question relating to vision has been so much debated as the cause of the single appearance of objects seen by both eyes” (Charles Wheatstone, 1838 ) The question…
Our visual perception arises from the interpretation of light information, which varies in space, wavelength, and time. It is the latter of these attributes that is explored in this chapter….
The limited behavioral repertoire of the infant and the impossibility of instructing the test participant have made it necessary for vision scientists interested in human visual development to adapt the…
Introduction The preceding chapters have described how visual signals pass from the retina to the visual regions of the brain. In this chapter we discuss how processing of these signals…
Introduction Over the last three decades it has been well documented that visual deprivation, especially when it occurs early in life, results in fundamental alterations of neural function across more…
Overview In many ways, primary visual cortex can be thought of as our mind’s eye. It sits at a pivotal location in our visual system, such that losing primary visual…
The lateral geniculate nucleus: the gateway to conscious visual perception Located one synapse from the retina, the lateral geniculate nucleus (LGN) of the thalamus is the main link between eye…
The bulk of the retina’s computing hardware is located in the inner retina. Here, dozens of neural circuits allow the retina to detect subtle changes in brightness, contrast, color, and…
Introduction The dorsal lateral geniculate nucleus of the thalamus (LGN) is the gateway through which visual information is transmitted from the retina to the cortex; therefore, conscious visual perception relies…
