The role of visual experience in the cortical topographic map reorganization following retinal lesions.
The mature visual cortex is capable of reorganizing its functional connections in response to retinal injuries. Although this phenomenon is well established, there are a number of unresolved issues. This paper will review some of the more critical aspects of adult plasticity including those based on our most recent findings. Our preliminary data indicate that a large-scale reorganization of cortical maps following retinal injuries may require an increase in synaptic strengths at key cortical sites promoted by long-term, repeated use.
