What if the aging brain isn't simply declining, but actually rewiring itself to become more efficient in unexpected ways?
In this fascinating exploration of brain health and aging, renowned expert Mark D'Esposito unravels the complexities of our brain's architecture, with special focus on the frontal lobe's crucial role in executive function. The episode challenges common misconceptions about cognitive aging, revealing how the brain demonstrates remarkable plasticity and adaptability as we age. Listeners will discover how the aging brain compensates for changes by recruiting additional neural resources and learn practical strategies for maintaining cognitive health through a holistic approach.
