The present disclosure provides methods for investigating neurogenesis, neural cell proliferation and differentiation. Specifically, the present disclosure relates to methods for identifying pharmaceutical agents capable of modulating neurogenesis and neural cell proliferation, methods of screening for genes that modulate neurogenesis and proliferation of neural progenitor cells, and methods of identifying pharmaceutical agents as candidate modulators of neurogenesis and neural proliferation or differentiation. The present disclosure also relates to methods for identifying pharmaceutical agents to characterize and modulate neurogenesis, pharmaceutical agents identified by such methods, methods for treating patients with such pharmaceutical agents, and compositions containing such pharmaceutical agents. Accordingly, the present methods enable elucidation of the mechanisms that control neurogenesis, brain development and function in healthy animals and in disorders of the nervous system. Furthermore, the present methods facilitate the development of compositions to prevent, improve or stabilize impaired neurogenesis in various nervous system disorders, including cognitive disorders.
