After the end of embryonic development in mammals, neurons are not produced in most of the areas of the central nervous system. Neurons degenerated by insults cannot be replaced by new ones in the adult brain. However, in the ventricular-subventricular zone (V-SVZ) located at the lateral walls of the lateral ventricles, neurons are continuously generated even in the adult brain. We are focusing on the behavior of the young immature neurons under physiological and pathological conditions.

The V-SVZ-derived new neurons migrate for a long distance in mature brain tissues containing many glial cells and neuronal fibers to modify neuronal circuit. In addition, in response to brain insults such as ischemic stroke, neurodegenerative diseases and traumatic injury, neuroblasts migrate toward the damaged area to regenerate neurons. Thus, the V-SVZ can be an endogenous source of new neurons that contribute to the regeneration of neuronal circuitry. However, this spontaneous process does not produce adequate neurological restoration. We aim to understand the mechanisms that regulate migration and differentiation of the new neurons and their roles in brain plasticity and regeneration in the adult brain. We further investigate efficient interventions that manipulate these endogenous processes to cause functional recovery.
