How Silence Affects Our Brains in A Good Way, Science Explains

How Silence Affects Our Brains in A Good Way, Science Explains

In a world that’s increasingly busy and loud, silence sells. Like clean water, silence is a resource, and can, in fact, be used as a selling point. Consider, your laptop that runs without a peep, meditation retreats, holiday getaways to remote locations, or those noise canceling headphones. Silence is the glue that binds them together.

Silence Has Been Studied by Accident

Over the years, research has emphasized how silence can calm our bodies, improve our connection with the world and actually increase the “noise” of our inner thoughts, with the majority of the research focusing on noise when coming to these conclusions, not silence.

Yes, most researchers have studied silence by accident. For instance, in a 2006 Study, where the physiological effects of music were studied, Luciano Bernardi said the following in Nautilus:

“We didn’t think about the effects of silence. That was not meant to be studied specifically.”

Nevertheless, what were the effects of silence on our brains in these studies?

Two Minutes of Silence Heightened Arousal

In the aforementioned study, Bernardi observed physiological metrics for two dozen subjects when they listened to six songs. According to Bernardi:

“During almost all sorts of music, there was a physiological change compatible with a condition of arousal.”

But what was even more surprising, was what happened when there were silent pauses – two minutes of silence proved far more relaxing than peaceful music or a longer silence played before the experiment started. One of his main findings – silence is heightened by contrasts – is supported by Neurological research, in a study by Michael Wehr in 2010.

Silence Affects Our Auditory Cortex

The 2010 study by Michael Wehr who was observing the brains of mice during short bursts of sound produced some surprising results. Whilst a burst of sound causes the auditory cortex (that part of the brain responsible for processing sound information), to light up, silence also causes a change. A separate network of neurons in the auditory cortex fire up. Wehr says:

“When a sound suddenly stops, that’s an event just as surely as when a sound starts.”

What though happens the moment the auditory cortex fires up?

How Silence Affects our Auditory Cortex: Cell Development

This question was examined by a Duke University regenerative Biologist, Imke Kirste. In the 2013 study, she was analyzing the effects sound has on the brains of adult mice. Four groups of mice were exposed to different auditory stimuli: music, baby mouse noises, white noise, and silence.

The silence was the control, and as with many previous studies, its effect was considered negligible. Once again though the findings were an eye-opener. All the sounds had a short-term neurological effect, but what about silence?

Two hours of silence per day led to cell development in the hippocampus – the brain area responsible for memory formation and emotions. This baffled Kirste. But after some thought she came to the following conclusion – the absence of noise was so artificial and alarming that it caused hyper-alertness in the mice.

Whilst new cell development isn’t always good for health, in this instance, the cells were becoming functioning neurons (a specialized cell that transmits nerve impulses; also known as a nerve cell). Kirste went on to say:

“We saw that silence is really helping the newly generated cells differentiate into neurons and integrate into the system.”

Silence Amplifies Self-Reflection

Not only does silence aid in cell generation, but it also aids in self-reflection. We all have what is known as the “default mode” of brain function – found in the prefrontal cortex (located in the front of the brain and responsible for abstract thinking, thought analysis and regulating thinking).

The default mode is always active, receiving and analyzing information. For example, the ability to detect danger happens automatically in this part of the brain. This default mode is also highly active during self-reflection (understanding ourselves) according to Joseph Moran who published a paper titled “What can the organization of the brain’s default mode network tell us about self-knowledge?”

According to Moran and colleagues, when the brain is in this resting mode, it is able to integrate internal and external information into a conscious workspace. When there is silence, your conscious workspace has greater freedom to process the internal and external information, allowing you to better discover your place in the world. Silence amplifies self-reflection.

And perhaps Noora Vikman, an ethnomusicologist (someone who studies music in a cultural context) and silence consultant for Finland’s marketers sums it up best:

“If you want to know yourself you have to be with yourself, and discuss with yourself, be able to talk with yourself.”

Silence then truly is golden. It changes your brain. It changes your life.

How to Tap into Your Right Brain’s Potential

How to Tap into Your Right Brain’s Potential

You may have heard someone say they are “totally right brained” or that they’re “a left brained person.”

There is a pervasive myth that’s been making its rounds for over a century: people have two hemispheres of their brains, and if they have a dominant left brain, they’re more analytical; and if they have a dominant right brain, they are more creative.

Before we go debunking this theory and then giving some tips for how people can access their creative brain centers, let’s first take a look at where the left brain/right brain lateralization theory comes from.

The Left Brain/Right Brain Lateralization Theory

In the 1800s, scientists discovered that when patients injured one side of their brains, certain skills were lost.[1] Scientists linked those different skills to one side of the brain or the other. Thus began the left brain/right brain myth that continues to this day.

Then, in the 1960s and 70s, Roger W. Sperry led 16 operations that cut the corpus callosum (the largest region that connects both brain hemispheres together) in order to try to treat patients’ epilepsy. Sperry wrote about the differences in the two hemispheres as a result of those surgeries.[2]

Sperry’s work was popularized in 1973 with a New York Times article about his lateralization theory—that people were either right brained (read: logical) or left brained (read: creative). From here, Sperry won the Nobel Prize for his work and numerous other publications spread the right brain/left brain myth.

Debunking the Right Brain/Left Brain Myth

If anything, the lateralization theory of the brain is a gross exaggeration. It is true that people have two hemispheres of their brains. It is also true that there are differences in the composition of those two hemispheres.

However, the hemispheres are actually much more interconnected than Sperry’s work initially made it seem.

In a 2013 study,[3] scientists scanned over 1000 people’s brains, checking for lateralization. They confirmed that certain brain functions occur predominately in one hemisphere or the other but that, in reality, the brain is actually much more interconnected and complex than the right brain/left brain lateralization theory makes it seem.[4][5]

A New Metaphor for Right Brain/Left Brain

How do we get past this right brain/left brain myth?

First, let’s look at what contemporary cognitive science says about brain regions, and creative and logical modes of thinking.

My background is as an improviser and improv researcher. I wrote Theatrical Improvisation, Consciousness, and Cognition and think looking at improvisation and the brain can shed light on a new model for talking about unlocking the brain’s creative potential.

Functional magnetic resonance imaging (fMRI) brain scans have shown that while trained improvisers improvise (musically on a keyboard, rapping, and comedic improvisation) an interesting shift happens in their brain activity. [6]

A region called the dorsolateral prefrontal cortex decreases in activity and creative language centers such as the medial prefrontal cortex increase in activity. The dorsolateral prefrontal cortex is linked with conscious thoughts—that inner voice that tells you not to say something or criticizes you when you do.

The medial prefrontal cortex is among the brain regions linked with creativity. So, instead of thinking about right brain and left brain, perhaps it’s more current and correct to think about more specific brain regions instead of hemispheres. Perhaps, it’s more useful to think about which activities and strategies will allow us to inhibit our dorsolateral prefrontal cortexes and allow our medial prefrontal cortexes to flourish.

How to Enhance Your “Right Brain” — Creativity

Whether we’re talking about right brain versus left brain, creative versus logical, or medial prefrontal cortex versus dorsolateral prefrontal cortex, we still know enough to talk about strategies to tap into your creative brain’s full potential.

So, now that we’ve dispelled the right brain/left brain myth and looked at a more contemporary, cognitive neuroscience theory of brain regions and creativity centers, let’s look at how to tap into the potential of your creative brain.

1. Performing Arts

One way to tap into your creative brain centers is to participate in the performing arts. Whether you improvise, act, or dance, the performing arts allow you an embodied experience that will help you snap out of your habitual, logical thoughts.

Another benefit of the performing arts is that it changes your attention. Attention and creativity are inextricably linked. When we improvise, act, or dance, we have to focus intently on our fellow performers. This means we are forced to focus less on our conscious, logical thoughts. This frees us up for more creative thinking and expression.[7]

One of the conclusions of my research on improvisation is that focusing intensely on fellow improvisers and the task at hand makes it more likely that we experience a flow state. Dr. Csikszentmihalyi,[8] a Professor of Psychology and Management defines flow as an optimal psychological state when our skills match the difficulty of the task at hand. Our perception of time is altered as we get into the zone and become more present and in the moment during our chosen activity.[9]

A flow state is a creative state. It’s the opposite of crunching numbers and forcing ourselves to work out a problem with the conscious regions of our brain. So, get up, improvise, act, or dance to access your creativity.

2. Visual Art

Art teacher Betty Edwards[10] wrote a book called Drawing on the Right Side of the Brain. Here again, we see that a shift in our attention can lead us to an increase in our creative thinking.

Edwards’ book gives art students tricks to shift the way they see the world. For example, one exercise encourages students to literally flip whatever it is they’re drawing upside down before they draw it. This forces budding artists to literally see the object in a new way. This shift allows them to focus more on the individual components and patterns of the object, which allows them to draw it better.

Shifting how we see things is another way we can access our creative brain centers. Take an art class to shut off your conscious, critical thoughts and start seeing things from a new, more creative perspective.

3. Zone Out

If there’s one thing creativity doesn’t like, it’s being coerced.

I think we’ve all felt that awful feeling of trying to force ourselves to be creative. When we force it, we’re really trying to force our logical brain regions to be creative. It’s like asking your gardener to perform your appendix surgery. It’s just not what she does.

Instead, stop forcing it. Take a break. Take a long walk or a relaxing bath or shower. Let your mind wander.

Whatever you do, stop forcing it. This break lets your creative centers rise to the surface of your attention and get heard.

4. Practice Mindfulness

The final trick to start accessing your so-called right brain is to practice mindfulness.

Now, there’s a lot of different ways to go about mindfulness. You can take a more physical approach with a yoga class. Or you can try meditating to become more aware and in tune with your thoughts and feelings: Meditation for Beginners: How to Meditate Deeply and Quickly

You could also try to incorporate fun mindfulness exercises[11] into your everyday routine like forcing yourself to go on detours or pretending you’re a detective who needs to examine people and places closely.

Any way you do it, mindfulness exercises and training can help you become better versed in how your brain works and what your normal thought process is like on a day-to-day basis. If we’re ever going to reach our optimal creativity, we have to become an expert in how our individual brain functions. Mindfulness is one way to become your very own brain expert.

Mindfulness also has added benefits like calming us, slowing our breathing, and helping us become more observant, which are also great ways to start tapping into our creative potential.

Final Thoughts

So, it may not be correct to say that our right brain is our creative brain, but it is still a valid pursuit to try to optimize our creative brain centers.

The key to do so is to relax, become observant, shift your perspective, move your body, try something new, and, whatever you do, don’t force it.

Creativity can feel slippery. It can abandon us when we need it most, but by slowing down and looking at things from a new perspective, we can give ourselves a better chance of tapping into our ultimate creativity, even if that doesn’t exactly mean our “right brain.”
