4 Ways How Meditation Changes Your Prefrontal Cortex (And How It Benefits You)

4 ways meditation changes your prefrontal cortex.

Your brain’s prefrontal cortex is extremely powerful.

Located right behind your forehead, it helps you rationalize (make decisions), pay attention (concentrate), regulate emotions and most importantly – think consciously (self awareness). It also gives you your sense of ‘self’! It is, in essence, the “control panel” of your brain!

So how does meditation affect the prefrontal cortex? Studies show that regular meditation thickens your prefrontal cortex, prevents it from shirking with age and also improves its connection with other areas of the brain like the amygdala helping you regulate emotions better.

Let’s look into these amazing changes in more detail, but before that, here’s are two reasons why the prefrontal cortex is so important.

1. Prefrontal cortex makes us human!

The relative size of the prefrontal cortex is also what separates us from the animals.

Studies have found that in human beings, the prefrontal cortex is almost 40% of the entire brain. For apes and chimpanzees, it is about 15% to 17%. For dogs it’s 7% and cats 3.5%.

Going by these values, it won’t be wrong to conclude that the reason why animals live in auto-mode and have little to no capacity to rationalize or think consciously is because of the relatively smaller prefrontal cortex.

Similarly, another interesting fact is that the relative size of the prefrontal cortex is what separates us from our primitive ancestors. Scientists have found that over the course of evolution, the prefrontal cortex is what grows the most prominently in humans, than in any other species.

Perhaps this is one of the reasons why the Hindu’s adorn this area with a red dot (on the forehead), also known as the bindi.

2. Prefrontal cortex is your brain’s control panel

As mentioned earlier, the prefrontal cortex is literally the ‘control panel’ of your brain.

But oddly enough, not many of us are in control of this control panel! There is a lot your can achieve when you take control of this control panel.

Here’s an analogy: If your brain/body was a horse, then the prefrontal cortex is the leash, upon holding which, you start to take back control over your brain (and body).

Amazing, isn’t it?

So how do you take control of the prefrontal cortex? Well, the secret lies in meditation and other contemplative practices like mindfulness. Let’s see why.

Meditation and the prefrontal cortex

Here’s are 4 ways how meditation positively impacts your prefrontal cortex.

1. Meditation activates and thickens your prefrontal cortex

Harvard neuroscientist Dr. Sara Lazar and colleagues studied the brains of meditators and found that their prefrontal cortexes were relatively thicker as compared to people who did not meditate.

She also found a direct correlation between the thickness of the prefrontal cortex and the amount of meditative practice. In other words, more experienced the mediator, the thicker her/his prefrontal cortex.

It has also been found that meditation in particular increased gray matter density in areas of the prefrontal cortex that are responsible for planning, decision making, problem solving and emotional regulation.

So one thing is clear; meditation activates your prefrontal cortex and in the long run, thickens it, boosting brain power, making you more conscious and in control of your brain!

2. Meditation strengthens connection between the prefrontal cortex and amygdala

It has been studied that the prefrontal cortex is connected to the amygdala (your stress center). The amygdala is an area of the brain that controls emotions. Because of this connection, the prefrontal cortex has the ability to moderate emotional responses.

Without the prefrontal cortex, we will not have any control over our emotions and will act out impulsively whenever an emotion takes over – very similar to how animals act.

Studies indicate that meditation actually strengthens connections between the prefrontal cortex and amygdala and thereby giving you better control over your emotions. Studies also indicate that the actual size of the amygdala got smaller and its connections to other primal parts of the brain lowered in experienced meditators.

Not only does this give you the ability to recover faster from emotional bouts but you also become more responsive as opposed to being impulsive and reactive to emotions.

This in turn gives rise to positive qualities like patience, calmness and resilience.

3. Meditation prevents the prefrontal cortex from shrinking

It is a well established fact that the prefrontal cortex starts to shrink as we age. This is why it is harder to figure things out and remember things as we grow older.

But research by Harvard neuroscientist Dr. Sara Lazar has also found that brains of experienced mediators who were 50 years old had the same gray matter in the prefrontal cortex as 25 year olds!

4. Meditation increases activity in your left prefrontal cortex which is associated with happiness

Dr. Richard Davidson, who is the professor of psychology and psychiatry in the University of Wisconsin–Madison found that when a person is happy, their left prefrontal cortex is relatively more active and when sad (or depressed) their right prefrontal cortex is active.

He also found that meditation actually increased activity in the left prefrontal cortex (thereby lowering activity in the right prefrontal cortex). So essentially, meditation actually makes you happy as per science.

More information on this research can be found in his book The Emotional Life of Your Brain (2012).

There are various other studies that have proven this to be true. For example, a study done on Richard Mathieu a Buddhist monk who has been practicing meditating for many years showed that Richard’s left prefrontal cortex was predominantly more active compared to his right prefrontal cortex. Subsequently, Richard was named the happiest man in world.

So these are just some known ways how meditation changes your brain and your prefrontal cortex and there is a good possibility that this is just the tip of the iceberg.
