5 Must Know Facts For Your Next Test

1. Neurogenesis can be influenced by dietary factors such as omega-3 fatty acids and antioxidants.
2. Chronic stress can inhibit neurogenesis, while physical exercise has been shown to promote it.
3. Neurogenesis declines with age but can be stimulated through certain nutritional interventions.
4. Nutrients like flavonoids found in fruits and vegetables may support neurogenesis and overall brain health.
5. Deficiencies in vitamins such as B12 and folate have been linked to impaired neurogenesis.
