An understanding of the normal processes of neuronal generation and migration is of great help in the recognition of these disorders. In this manuscript, we have attempted to present this information, as well as the clinical, pathologic, and imaging manifestations of these disorders, in order to aid in the understanding, and, hopefully, the diagnosis of these disorders. Figure 36 summarizes the many findings in these disorders.
