5 Must Know Facts For Your Next Test

1. The prefrontal cortex plays a crucial role in executive functions including planning, impulse control, and attention.
2. Proper nutrition can influence the development and functioning of the prefrontal cortex throughout the lifespan.
3. Deficiencies in essential nutrients like Omega-3 fatty acids, vitamins B6 and B12 are linked to impaired prefrontal cortex function.
4. Antioxidants from fruits and vegetables support prefrontal cortex health by reducing oxidative stress.
5. Poor dietary habits during critical periods of development can lead to long-term consequences on prefrontal cortex functionality.
