Neurogenesis is the process by which new neurons are formed in the brain. This process is most active during embryonic development, where it plays a crucial role in shaping the nervous system. However, research has shown that neurogenesis continues in specific regions of the adult brain, notably the hippocampus—a region integral to memory and learning.
In adults, neurogenesis is believed to contribute to cognitive functions such as learning and memory, as well as emotional regulation. Factors like physical exercise, enriched environments, and certain pharmacological treatments have been shown to enhance neurogenesis, while stress and aging may inhibit it.
The extent and functional significance of adult neurogenesis in humans remain areas of active research, with ongoing debates about its prevalence and impact on brain function.
