Why Introverts Are Introverts? Because Their Brains Are Different

Why Introverts Are Introverts? Because Their Brains Are Different

You prefer to curl up and read a book by yourself over going to a flashy social event. You like the company of one close friend rather than a group of many rowdy people. Once more you prefer to stay on the safe side than take risks. Does this sound familiar? If so, then you are probably an introvert. You may already know this but what you may not be aware of is that there are physical differences in your brain that make you prefer quiet activities over those that are highly energized.

Carl Jung’s studies

It was Carl Jung who in the 1920s coined the terms introvert and extrovert. He did so to describe contrasting personality types and to explain why different people were energized in distinct ways. He hypothesized that extroverts gained their energy from their social interactions and eternal environments and tended to feel uncomfortable and anxious when they found themselves alone.

Introverts, on the other hand, Jung explained, are able to replenish their energy levels when they are in quiet environments. Unlike extroverts they find socializing and busy environments overstimulating and too demanding.

Dr. Laney clarifies in her book, The Hidden Gifts of the Introverted Child that “introversion and extroversion are not black and white. No one is completely one way or another – we all must function at times on either  side of the continuum”.

Introversion and extroversion are at the opposite ends of the same spectrum. Everybody moves up and down the spectrum depending on external and internal factors, however, a person tends to prefer one personality type over the other.

The Dopamine difference

A major difference between the brains of introverts and extroverts is the way they react to the neurotransmitter dopamine.

Dopamine is a chemical that is released in the brain. It gives a person their motivation to achieve external goals and receive external rewards. For example, dopamine may motivate an individual to earn more money, increase their circle of friends, attract a good looking partner or advance to a higher role at work. When dopamine is released all of us become more alert to our surroundings, more talkative and more motivated to undertake activities that may be perceived as risky.

Introverts and extroverts have equal amounts of dopamine in their brains, however, the difference between these two categories of people is the activity of the dopamine reward network. The dopamine reward network is more active and dynamic in the brains of extroverts as Scott Barry Kaufman, the Scientific Director of The Imagination Institute says. When an extrovert anticipates a social event, for example, they feel good and energized, whereas the introvert will feel overstimulated.

Acetylcholine and Introverts

Christine Fonseca writes in her book Quiet Kids: Help your introverted child succeed in an extroverted world that introverts prefer to rely on a different neurotransmitter called acetylcholine.

Acetylcholine is related to pleasure, just like dopamine, however acetylcholine makes a person feel good when they turn inward. It gives a person the skill to reflect and focus solely on an individual task for an extended period of time. As it is simpler to turn inwards when there is limited external stimulation, introverts opt for a calm environment.

Introverts prefer one side of the nervous system over the other

The nervous system is divided into two distinct parts: there is the sympathetic side which is related to the “fight, fright, or flight” response; and the parasympathetic side. The parasympathetic side allows us to rest and digest.

When the sympathetic side is stimulated the body prepares for action; adrenaline is released, glucose energizes the muscles and the amount of oxygen in the body increases. The thinking mechanisms in the brain are put on hold. Dopamine increases alertness in the rear of the brain.

When the parasympathetic side of the brain is in gear; muscles relax, energy is stored and food is metabolized. Blood flow and alertness in the front of the brain increase as acetylcholine is released.

Although extroverts and introverts use both sides of the nervous system, various times introverts tend to prefer to use the parasympathetic side. This allows introverts to be calm and to act in a slow and measured way.

Why introverts tend to overthink

When information from the external world is received by an extroverts brain it travels via a short pathway that goes through the areas of the brain where touch, taste, sound and sight are processed.

When introverts receive stimulus from the outside world the pathway that the information travels through is a lot longer. The information goes through many areas of the brain including:

  1. The right front insular,
  2. Broca’s area,
  3. The right and left front lobes and,
  4. The left hippocampus.

The right front insular is an area involved with empathy, emotional thought and self-reflection. The Broca’s area activates self-talk and plans speech. The right and left front lobs, plan and select ideas and actions. The left hippocampus decides what things are personal and places them in long-term memories.

The long journey that the information takes when an introvert receives stimulus from the external world is the reason that introverts take longer to speak, react and make decisions.

Introverts have more gray matter in the front of their brains

study published in the Journal of Neuroscience discovered that introverts have larger, thicker gray matter in their prefrontal cortex. The prefrontal cortex is the place in the brain that is linked to abstract thought and decision-making. Extroverts, on the other hand, have thinner gram matter in the same area.

What does this mean? It means that introverts devote more of their energy and resources to abstract thought while extroverts have the propensity to live in the moment.

Summation

Things may now make more sense to you, as an introvert. You can now understand that there are physical differences in your brain that make you prefer peaceful activities and self-reflection over highly energized situations.

7 Signs of an Unhappy Relationship That Makes You Feel Stuck

7 Signs of an Unhappy Relationship That Makes You Feel Stuck

Relationships are complicated and when you’re unhappy, it can be difficult to tell what’s causing it and what needs to change.

Sometimes it’s as easy as opening up to your partner about your problems, while other times it may be necessary to switch partners or roll solo to get your mind straight.

When you’re in the thick of things, it can be difficult to tell if you’re unhappy in your relationship or just unhappy in general (in which case, a relationship may be just the cure you need).

Here’re signs of an unhappy relationship that is possibly making you feel stuck:

1. You’re depressed about your home life.

No matter what you do in life, you’re going to have good and bad days. Your relationship is no different.

However, no matter what you’re going through at home, you have to feel comfortable in your own home.

If you constantly dread going home because your significant other is there, there’s a problem. Maybe it’s something you already know about, everyone has an argument or just needs some alone time.

When that yearning to be alone becomes an insatiable obsession over the course of months and years, it’s time to realize you’re not the exception to the rule.

You’re unhappy in your relationship, and you need to take a look in the mirror and do whatever it takes to make yourself smile.

2. You aren’t comfortable being yourself.

Remember all those things you discovered about yourself when you first got together? The way your partner made you feel when you met that made you fall in love with him or her in the first place.

If they don’t make you feel that way anymore, it’s not the end of the world. If your partner makes you uncomfortable about being you, then her or she is only dragging you down. It’s up to you to decide how to handle that.

You need to be comfortable with who you are. This means being comfortable in your skin and with the way you walk, talk, look, breath, move, and all the other things that make you uniquely you.

If the person who supposedly loves you doesn’t make you feel good about yourself, know that you can do better. They’re not even one in a billion.

3. You can’t stop snooping.

Mutual trust is necessary in any relationship. The only way to get that trust is with respect.

I can find you anywhere online, no matter how private and secure you think you are. The odds of you having a password I can’t crack are slim. If we’ve met in person, I could install a remote key logger on your device without even touching it.

Finding your information online hardly takes a clandestine organization. Any idiot with a Wi-Fi-enabled device can cyberstalk you. I’m just the only idiot in the village admitting it.

So now that we know everyone snoops, it’s time to address your personal habits. Governments snoop because they don’t trust us. If you’re snooping on your partner, it’s because you don’t trust them.

It’s ok to have doubts, and it’s perfectly normal to look into anything that looks weird, but keep in mind that data collection is only half of an investigation.

If you find yourself constantly snooping and questioning everything, clearly there’s a trust issue and the relationship likely needs to end.

4. You’re afraid of commitment.

If you’ve been dating longer than a year and you aren’t engaged, it’s never going to happen.

Commitment is important. People will come up with a million ways to describe why they can’t be committed.

No matter who you are if you like it, you need to put a ring on it. Find an engagement ring, stick a gemstone in it and marry the person. If you’re not legally able to get married or you don’t believe in it for one reason or another, have a child (or adopt one, however you’re able to) or treat your partner’s family like your own. It’s a huge financial and mental commitment.

If you’re not ready for one or the other after some time, don’t waste anymore of your precious life on the relationship.

Your relationship should be something that propels you forward. If it’s not going anywhere, make it an open relationship and call it what it is—dating multiple people.

5. You imagine a happier life without your partner.

If all you’re doing is imagining a happier life without your partner, it’s a sign that you’re in the wrong relationship. You’re unhappy and you need to get out.

Your partner should be included in your dreams. There’s nothing wrong with wanting a future with someone.

Try to remember what you dreamed of before you got your heart broken by the realities of life, love and the pursuit of human success.

Remember when you would crush on that cute kid in class? You would secretly imagine marrying him or her and going on an adventure—that’s the way life should be.

If you’re not at least imagining adventures together, then why are you in that relationship?

6. You resent, rather than love your partner.

When a relationship starts to crumble, you begin to resent your partner for all the things you once loved about him or her.

When you’ve reached this point, your partner has reached at least No. 2 on this list. From your partner’s perspective, your unhappiness with them is picked up as bashing them for being who they are.

If you’re both unhappy in the relationship, it’s better if it ends as quickly and painlessly as possible.

7. You chase past feelings.

It’s okay to reminisce about the past, but if all you do is wish things were like they used to be, it’s a sign you’re not on the right path.

You’re unhappy and, at the very least, you need to have an open dialogue about it. This isn’t necessarily a sign that the relationship should end, but it definitely needs a spark.

When you talk to your partner candidly about what it is you’re looking for, you never know how they’ll react. The risk alone is worth it, good or bad.

Final thoughts

If you’re feeling stuck in your current relationship, it’s time to reflect about it with your partner. Don’t ignore these signs of an unhappy relationship as they will slowly go worse and harm both you and your partner in long-term.
