Excerpt
The role of neurologists in diagnosing and treating diseases of the nervous system also affords an opportunity to learn about the function of the nervous system. The advent of new imaging techniques has greatly expanded this opportunity. Precise localization of lesions by magnetic resonance imaging and delineation of disturbed function of certain brain areas by positron emission tomography have led to new ideas on brain-behavior linkages and to novel hypotheses about neural organization. One group of investigators using some of these techniques, along with extensive neuropsychological testing, has shown that specific types of memory may have quite diverse localization in the brain.1 This alters the traditional view that memory is largely stored in one neural system. They also propose that neural processing takes place in convergence zones. Thus, there are a series of regions with information moving forward and backward so that final representation in the convergence zone is
