This post has been updated since it’s original publish date. What part of the brain makes up about 30 percent of the total human brain – compared with just 11 percent for chimpanzees, 7 percent for dogs, 3 percent for cats (perhaps why they need nine lives), and 1 percent for mice (perhaps why they’re eaten by cats)? If you guessed the prefrontal cortex (PFC), you’re right.

What is the “Executive Center” of the Brain?

Your brain is responsible for every aspect of your life—how you think, how you feel, how you act, and how you interact with others. But do you know which region of the brain plays the biggest role in your ability to think, problem-solve, plan ahead, and communicate effectively? It’s the prefrontal cortex, otherwise known as the executive center of the brain. This region makes up about 30% of the total human brain. Compare that with just 11% for chimpanzees, 7% for dogs, 3% for cats, and 1% for mice. Learning to love and care for your brain’s executive center can mean the difference between struggling in life or living the life you want. Healthy habits contribute to a well-functioning brain while unhealthy habits increase the risk of brain dysfunction.

PREFRONTAL CORTEX BASICS

The prefrontal cortex (PFC) is the most evolved part of the brain. It occupies the front third of the brain, behind the forehead. The PFC is divided into three sections: • Dorsal lateral section, located on the outside surface of the PFC • Inferior orbital section, located on the front undersurface of the brain • Anterior cingulate gyrus, running through the middle of the frontal lobes The PFC is involved with executive functions, such as: • Focus • Empathy • Judgment • Organization • Impulse control • Learning from mistakes Our ability as a species to think, plan ahead, use time wisely, and communicate with others is heavily influenced by this part of the brain. The PFC is responsible for helping you be goal-oriented, socially responsible, and productive in every area of your life. Brain-imaging research shows that the PFC continues to develop throughout childhood, into late adolescence, and even into a person’s mid-20s. As such, an individual’s daily habits greatly impact how the brain develops. The brain-imaging work using SPECT scans at Amen Clinics clearly shows that healthy habits contribute to a well-functioning brain while unhealthy habits increase the risk of brain dysfunction.

THE PREFRONTAL CORTEX AND SELF-CONTROL

Why are some people able to say no to cocktails, drugs, potato chips, gambling, and other behaviors that aren’t good for them, while others impulsively partake in risky activities? It has to do with self-control. In large part, self-control is tied to the PFC. When the brain’s reward system drives you to seek out things that bring you pleasure, it’s the PFC that puts on the brakes to prevent you from engaging in risky behavior. In a healthy self-control circuit, an effective PFC provides impulse control and good judgment. At the same time, the reward system offers an adequate dose of motivation, so you can plan and follow through on your goals. But what happens when the PFC isn’t working well?

PROBLEMS IN THE PFC

Think of the PFC as your boss at work. When the PFC is low in activity, it’s as if the boss is on vacation, so there’s little to no supervision and nothing gets done. On the other end of the spectrum, when the PFC works too hard, it’s as if the boss is micromanaging everyone and people are left with anxiety and worry. Decreased activity in the PFC has been associated with lack of forethought, poor judgment, impulse control problems, and poor internal supervision. If the PFC is underactive, it can create an imbalance in the reward system and cause you to lose control over your behavior. When this is the case, you’re more likely to fall victim to your cravings.

HEAD INJURIES AND THE PFC

Due to its location, the PFC is especially susceptible to concussions. Unfortunately, much of the PFC sits on top of several sharp, bony ridges inside the skull, and it lies just behind the area where many blows to the head occur. Your brain wasn’t made to endure the punishment of soccer headers, tackle football, or boxing. Even mild traumatic brain injuries (mTBI) can have far-reaching health consequences. Post-concussion syndrome can lead to brain fog, aggression, substance abuse, and more. A growing body of research shows that head injuries are a major cause of psychiatric disorders including anxiety, depression, and even memory issues and Alzheimer’s disease. ADD/ADHD AND THE PFC Attention-deficit/hyperactivity disorder (ADHD), also referred to as attention-deficit disorder (ADD), typically occurs as a result of neurological dysfunction in the PFC. When people with ADD/ADHD try to concentrate, PFC activity tends to decrease. Normally, the PFC sends inhibitory signals to certain areas of the brain, quieting stimulation from the environment so that you can concentrate. When the PFC is underactive, it doesn’t adequately dampen the sensory parts of the brain. As a result, too many stimuli bombard the brain at once. For those who struggle with ADD/ADHD, distractibility is evident in many different settings. Common ADD/ADHD symptoms include:

• Poor internal supervision
• Short attention span
• Disorganization
• Hyperactivity (although only half the people with ADD are hyperactive)
• Difficulty learning from past errors
• Lack of forethought
• Procrastination

Without proper PFC function, it’s difficult to act in consistent, thoughtful ways, and impulses can take over. Impulse control problems may lead to behaviors such as lying, stealing, having affairs, or excessive spending. Increased death rates have been associated with impulsive behaviors, such as: tobacco use, poor diet, excessive alcohol use, violence, risky sexual behavior, aggressive driving, suicide, and drug use. According to research, these factors can have a huge impact on a person’s longevity.

4 WAYS TO STRENGTHEN THE EXECUTIVE CENTER OF YOUR BRAIN 

1. Get your heart pumping.

Exercise is literally the fountain of youth. It boosts blood flow to the brain and increases chemicals that are important for learning, memory, and stimulating the growth of new brain cells. Exercise boosts blood flow to the PFC, which can help you be more productive. Try to exercise at least 30 minutes every day. 

2. Get adequate sleep.

While you sleep, your brain is still working hard to carry out essential tasks. According to a 2019 study, as you slumber, your brain washes itself, clearing away toxins and neural debris that has accumulated during the day. When your brain doesn’t take out the “neural trash,” it accumulates and contributes to sluggish brain function. Sleep disorders can lead to brain and mental health problems, such as slower reaction times, brain fog, and poor decision-making. To keep your executive center operating at peak condition, it’s recommended that you get 7 to 9 hours of sleep every night. 

3. Balance your blood sugar.

Low blood sugar levels are associated with lower overall blood flow to the brain, poor impulse control, irritability, and bad decisions. Basically, it drains your executive center. For optimal executive center function, keep your blood sugar balanced throughout the day with healthy snacks. Also, supplements, green tea, and Rhodiola can increase blood flow to the PFC which can help you make better decisions.

4. Ask yourself this question.

Whenever you’re about to make a decision, ask youself, “Then what?” When it comes to your health, these are the two most important words in the English language. Think about the consequences of your behavior before you act. Exercising self-control is one of the best ways to strengthen your PFC. To develop your PFC, you can practice saying no to the things that aren’t good for you and, over time, you’ll find it easier to do the right thing.

SUPPORT YOUR PFC

Taking care of your brain is the single most important thing you can do for your health, your life, and the lives of those around you. When your executive center works optimally, it helps you be smarter, healthier, happier—and even wealthier. Isn’t that what you want? ADD/ADHD and other mental health issues can’t wait.
