With age, there is a decrease in adult neurogenesis, which is associated with a decrease in cognitive functions. Newly formed neurons and «immature» neurons together constitute a potential reservoir of young cells («brain reserve») that can be used to prevent aging and/or delay the onset/reduce the impact of neurological disorders.The possibility of using neurogenic processes for therapeutic purposes to reduce pain and improve the quality of life of patients is implied.neurogenesisneuronsbrainneurologyhealth careнейрогенезнейроныголовной мозгневрологияздоровьесбережение[Triarhou L.
