 The Reactivation and Reorganization of Retinotopic Maps in Visual Cortex of Adult Mammals After Retinal and Cortical Lesions

Show Summary Details

Preview

The mammalian visual system is characterized by a hierarchy of processing stations that tend to preserve and reflect the spatial order of outputs from the retina of each eye. The optic nerve fibers maintain much of the spatial organization as they leave the eye, and refine that order as they terminate in their major brainstem targets: the dorsal lateral geniculate nucleus (LGN) and the superior colliculus. A retinotopic pattern is preserved in the LGN projections to primary visual cortex and in at least several other areas devoted to the early stages of cortical processing of visual information. This chapter considers what happens to these orderly representations of the retinal outputs when some part of the retina is missing.
