Neurogenesis is the process by which new neurons, or nerve cells, are formed in the brain. This process primarily occurs in the hippocampus, a region associated with memory and learning. Neurogenesis plays a crucial role in brain plasticity, allowing the brain to adapt and reorganize itself in response to new experiences. Factors such as exercise, diet, and stress can influence the rate of neurogenesis. Regular physical activity and a healthy diet can promote the growth of new neurons, while chronic stress may hinder this process. Understanding neurogenesis is important for developing strategies to enhance brain health and cognitive function.
