For example, there are factors that, when present at midgestation, disturb neuronalmigration and differentiation. If neuronalmigration is disrupted, an abnormality in cell position results. From a molecular standpoint, successful neuronalmigration during brain development is contingent upon the orchestrated expression of a series of trophic factors and guidance molecules. The third step involves neuronalmigration to their eventual target locations (8th to 15th week of gestation). Neuronalmigration, which occurs as early as the second month of gestation, is controlled by a complex array of chemical guides and signals. If confirmed, these findings would thus serve to link theories of abnormal neuronalmigration and the miswiring of connections. Abnormal cortical migration and the resultant abnormal neuronal networks could both generate seizures in the neuronalmigration disorders. It might be a component of other multi-subunit enzyme complexes, in which haplo-insufficiency can adversely affect the cellular mechanisms that are involved in neuronalmigration. Although aberrant neuronalmigration has been the interpretation most commonly invoked for cytoarchitectural abnormalities, there are other possible explanations. For example, in disorders in which either cell proliferation or neuronalmigration is disrupted in some way, either fewer neurons or abnormally positioned neurons result. Most infants with a neuronalmigration disorder appear normal, but some disorders have characteristic facial or skull features. Numerous genes are involved in neuronalmigration, and mice with spontaneous genetic mutations or experimentally induced (knockout) mutations have been very instructive in delineating mechanisms of neuronalmigration. Dyx1c1 functions in neuronalmigration in developing neocortex. Future research will attempt to address these issues by generating knockout mice that will be used to examine the resulting neuronalmigration patterns. They contribute to the formation of the blood-brain barrier, direct neuronalmigration, provide energetic support to neurons, and regulate the extracellular concentration of various ions, metabolites and neurotransmitters. There is also a loss of the normal neuronalmigration pattern within the inner layers of the cerebral cortex, the brain region responsible for higher mental processing. Researchers have suggested that mutations of these factors will be found in a number of neuropsychiatric disorders in which subtle abnormalities of neuronalmigration and architecture have occurred. One aspect of that maturation is a morphologic change from the long processes needed for guiding neuronalmigration to shorter but more processes with greater connectivity among cells. Astroglial cells that play a role early in gestation as the radial glial cells for neuronal migration are also crucial for later connectivity and the production of neural growth factors.
