How to Train the Brain: Strategies to Support Your Executive Function
Cognitive function expert Dr. Mark D'Esposito joins us to explore how we navigate life’s challenges, and how the prefrontal cortex plays a crucial role in helping us plan, organize, and make decisions. In this episode, we dive deep into cognitive control and executive function, uncovering how these processes govern our daily behavior. Dr. D'Esposito, a leading neuroscientist in the field, explains that cognitive control, anchored in the prefrontal cortex, allows us to act according to our goals rather than impulsively reacting to the environment. "It's what makes us human," he notes.
However, cognitive function is not immune to stress. Factors such as sleep deprivation, emotional strain, and poor nutrition can impair the prefrontal cortex, leading to poor decision-making and diminished self-regulation. By learning to protect and enhance this area of the brain, we can improve cognitive resilience in our everyday lives.
"Individuals with a higher baseline of dopamine have a higher working memory capacity." -Dr. Mark D'Esposito
Key Takeaways:
The prefrontal cortex governs planning, decision-making, and cognitive control.

A second critical component of cognitive function is dopamine, which plays a significant role in working memory. Working memory is the brain's ability to hold and manipulate information over short periods, vital for tasks ranging from simple calculations to complex planning. Dr. D'Esposito emphasizes that individuals with higher dopamine levels exhibit better cognitive function, and personalized interventions can optimize dopamine for enhanced brain performance.
Lastly, brain network modularity—the way various brain regions interact—predicts cognitive resilience and recovery. Those with higher modularity are more likely to respond positively to cognitive interventions, which could lead to breakthroughs in personalized medicine for aging and brain health.
Understanding cognitive function can transform how we approach mental sharpness and resilience. Programs like the Brain Health Project offer structured ways to improve cognitive capacities, integrating nutrition, stress management, and cognitive exercises.
