5 Things That Happen to Your Brain When You Experience Complete Silence

Scientists have studied the effects of silence on the brain for several decades, but a few studies are paramount in their importance if we are to understand just how vital silence is for a human being.

“Silence is the perfectest herault of joy. I were but little happy if I could say how much.” – Shakespeare

The word noise comes from a Latin root word meaning, “pain,” or “distress.” Noise is something we’ve become accustomed to, even if we are keenly aware of its ability to cause multiple forms of anguish. Even if we live in decibel hell,” we can find moments of silence to reduce our pain. We can intuitively observe that silence, in contrast, reboots our ability to think straight, and offers us a profound feeling of peace.

Silence also allows us to get to know our deepest truths in an undeniable way. It is in complete silence that the thoughts we shelter from others come to the surface.

But what else happens to us when we take a break from the deafening sounds of modern life? Aside from the metaphysical benefits of sitting in silence, there are staggering physiological changes which take place throughout the body: notably in the brain.

Scientists have studied the effects of silence on the brain for several decades, but a few studies are paramount in their importance if we are to understand just how vital silence is for a human being.

Silence Develops New Brain Cells

One study, published in the journal, Brain, Structure, and Function observed mice under the influence of noise and silence. The way the study was structured, silence was expected to be the control (identifiable or observable fact meant to minimize the effects of independent variables in a study). However, mice exposed to two hours of complete silence daily developed a peculiar side effect – they started to develop brand new cells in the hippocampus of the brain, the area which is associated with learning new things, retaining memory, and processing emotion. Though new brain cells don’t always directly translate into better health, one of the researchers, Imke Kirste, says that these new cells appeared to become functioning neurons.

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

Silence Heightens Sensitivity And Empathy

There are many brain areas associated with emotional sensitivity and empathy. Particularly, the right supramarginal gyrus, is an imperative brain region for the development of these traits.  If this brain region doesn’t function properly on a regular basis — or when we need to make particularly quick decisions — our ability to execute empathy is dramatically reduced.

When we spend time in silence, this area of our brains, along with others which support empathy, are allowed to rest and re-activate, building higher levels of empathic experience.

Silence Fights Insomnia

One study, published in JAMA measured the effects of silence on sleep. Though it was used to test mindfulness meditation, the essence of the meditation is to observe the thoughts, silently. Those who spent just twenty minutes practicing “silence” had a measured increase in sound sleep and no longer suffered from insomnia.

The Brain Evaluates And Internalizes Information

“You throw thorns, in my silence they become flowers.” – Gautama Buddha

Another important study has found that the brain processes information very differently when we allow it to be in silence. When the brain is at rest, meaning, it is not exposed to new stimuli via sound, it can take both internal information (learned things) and integrate them more seamlessly with external information.

In other words, instead of reacting to external stimuli, including things that would normally trigger us to behave in a less-than-conscious way, we can quickly determine how to integrate experiences with people, circumstances, and more.

Although we can’t impose a quiet environment in our own minds, and always calm our personal thoughts, it seems that a quiet external environment allows the famous “gap” in our thinking which Daoists, Buddhists, and others have hinted at. This gap is a split second of calm which allows us to choose our reaction to the world, instead of acting out old habits.

As Nietzsche once said, “Silence is worse, all truths that are kept silent become poisonous.” What better way to see the world as it truly is, and not as we’ve erroneously imagined it, then by getting a daily dose of silence?

Silence Releases Tension From the Body and Brain

Even two minutes of silence can release built up tension in the brain and the body.

Multiple studies that measured changes in heart rate, respiratory rates, carbon dioxide levels, cerebral-artery flow, and other concrete physical changes, found that just a few moments of silence change how our bodies respond to the world.

Preliminary studies even indicate that silence can help us to overcome childhood trauma, PTSD, and other serious conditions of the heart and mind. The amygdala — associated with memory formation and emotion — is activated when we hear “noise” leading to the release of stress hormones. Conversely, silence activates the release of oxytocin, GABA, and serotonin – all hormones which reduce stress.

In closing..

Silence is much more important to our brains than we’ve previously thought. All profound internal progress – our a-ha moments – are preceded by silence.

Physicists Suggest All Matter Could Be Made Up of Energy ‘Fragments’

Avatar

Published

on

Matter is what makes up the Universe, but what makes up matter? This question has long been tricky for those who think about it – especially for the physicists.

Reflecting recent trends in physics, my colleague Jeffrey Eischen and I have described an updated way to think about matter. We propose that matter is not made of particles or waves, as was long thought, but – more fundamentally – that matter is made of fragments of energy.

From Five to One

The ancient Greeks conceived of five building blocks of matter – from bottom to top: earth, water, air, fire and aether. Aether was the matter that filled the heavens and explained the rotation of the stars, as observed from the Earth vantage point.

These were the first most basic elements from which one could build up a world. Their conceptions of the physical elements did not change dramatically for nearly 2,000 years.

Then, about 300 years ago, Sir Isaac Newton introduced the idea that all matter exists at points called particles. One hundred fifty years after that, James Clerk Maxwell introduced the electromagnetic wave – the underlying and often invisible form of magnetism, electricity and light.

The particle served as the building block for mechanics and the wave for electromagnetism – and the public settled on the particle and the wave as the two building blocks of matter. Together, the particles and waves became the building blocks of all kinds of matter.

This was a vast improvement over the ancient Greeks’ five elements but was still flawed. In a famous series of experiments, known as the double-slit experiments, light sometimes acts like a particle and at other times acts like a wave. And while the theories and math of waves and particles allow scientists to make incredibly accurate predictions about the Universe, the rules break down at the largest and tiniest scales.

Einstein proposed a remedy in his theory of general relativity. Using the mathematical tools available to him at the time, Einstein was able to better explain certain physical phenomena and also resolve a longstanding paradox relating to inertia and gravity.

But instead of improving on particles or waves, he eliminated them as he proposed the warping of space and time.

Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the Universe. Instead of basing the theory on the warping of space and time, we considered that there could be a building block that is more fundamental than the particle and the wave.

Scientists understand that particles and waves are existential opposites: A particle is a source of matter that exists at a single point, and waves exist everywhere except at the points that create them.

My colleague and I thought it made logical sense for there to be an underlying connection between them.

Flow and Fragments of Energy

Our theory begins with a new fundamental idea – that energy always “flows” through regions of space and time.

Think of energy as made up of lines that fill up a region of space and time, flowing into and out of that region, never beginning, never ending and never crossing one another.

Working from the idea of a universe of flowing energy lines, we looked for a single building block for the flowing energy. If we could find and define such a thing, we hoped we could use it to accurately make predictions about the Universe at the largest and tiniest scales.

There were many building blocks to choose from mathematically, but we sought one that had the features of both the particle and wave – concentrated like the particle but also spread out over space and time like the wave.

The answer was a building block that looks like a concentration of energy – kind of like a star – having energy that is highest at the center, and that gets smaller farther away from the center.

Much to our surprise, we discovered that there were only a limited number of ways to describe a concentration of energy that flows. Of those, we found just one that works in accordance with our mathematical definition of flow.

We named it a fragment of energy. For the math and physics aficionados, it is defined as A = -⍺/r where ⍺ is intensity and r is the distance function.

Using the fragment of energy as a building block of matter, we then constructed the math necessary to solve physics problems. The final step was to test it out.

Back to Einstein, Adding Universality

More than 100 ago, Einstein had turned to two legendary problems in physics to validate general relativity: the ever-so-slight yearly shift – or precession – in Mercury’s orbit, and the tiny bending of light as it passes the Sun.

These problems were at the two extremes of the size spectrum. Neither wave nor particle theories of matter could solve them, but general relativity did.

The theory of general relativity warped space and time in such way as to cause the trajectory of Mercury to shift and light to bend in precisely the amounts seen in astronomical observations.

If our new theory was to have a chance at replacing the particle and the wave with the presumably more fundamental fragment, we would have to be able to solve these problems with our theory, too.

For the precession-of-Mercury problem, we modeled the Sun as an enormous stationary fragment of energy and Mercury as a smaller but still enormous slow-moving fragment of energy. For the bending-of-light problem, the Sun was modeled the same way, but the photon was modeled as a minuscule fragment of energy moving at the speed of light.

In both problems, we calculated the trajectories of the moving fragments and got the same answers as those predicted by the theory of general relativity. We were stunned.

Our initial work demonstrated how a new building block is capable of accurately modeling bodies from the enormous to the minuscule. Where particles and waves break down, the fragment of energy building block held strong.

The fragment could be a single potentially universal building block from which to model reality mathematically – and update the way people think about the building blocks of the Universe.

Neuroscientist Claims That Consciousness Itself Is Its Own Energy Field

Justin MacLachlan

Published

on

A neuroscientist has suggested in a new theory that our consciousness is derived from a field of electromagnetic waves given off by neurons.

The study published last month in the journal Neuroscience of Consciousness is entirely based off a theory absent of tangible evidence. However, the author of the research Johnjoe McFadden said that his hypothesis could offer a way forward for robots that think and feel emotions.

McFadden believes that neuron waves of electrical activity get sent out and as they propagate across the brain, they help compose our entire conscious experience.

Johnjoe McFadden, is a molecular geneticist and director of quantum biology at the University of Surrey. McFadden points to flaws in other models of consciousness as the reason that we don’t have sentient artificial intelligence or robots capable of achieving consciousness.

McFadden’s hypothesis swerves away from most traditional neuroscientists, who generally see consciousness as a narrative that our brain constructs out of our senses, perceptions, and actions. Instead, McFadden returns to a more empirical version of dualism — the idea that consciousness stems from something other than our brain matter.

McFadden’s theory adapts the idea of “dualism,” which is the belief that consciousness is a supernatural force. Dualism has long been rejected by scientists and ruled pseudo-science, but McFadden has attempted to apply a scientific explanation for the idea, which hasn’t been done before.

Neuroscience news reports that the theory is based on scientific fact:

“The theory is based on scientific fact: when neurons in the brain and nervous system fire, they not only send the familiar electrical signal down the wire-like nerve fibres, but they also send a pulse of electromagnetic energy into the surrounding tissue. Such energy is usually disregarded, yet it carries the same information as nerve firings, but as an immaterial wave of energy, rather than a flow of atoms in and out of the nerves.”

It’s also a fact we have an electromagnetic field surrounding our brain is well-known and is detected by brain-scanning techniques such as electroencephalogram (EEG) and magnetoencephalography (MEG) but has previously been dismissed as irrelevant to brain function and supernatural. Instead, McFadden contends that the brain’s information-rich electromagnetic field is, in fact, itself the seat of consciousness, driving the ‘free will’ of an individual.

“How brain matter becomes aware and manages to think is a mystery that has been pondered by philosophers, theologians, mystics and ordinary people for millennia,” McFadden said in a press release published by Medical Xpress. “I believe this mystery has now been solved, and that consciousness is the experience of nerves plugging into the brain’s self-generated electromagnetic field to drive what we call ‘free will’ and our voluntary actions.”

Ann Arbor becomes latest city to decriminalize “magic” mushrooms and other natural psychedelics

Elias Marat

Published

on

(TMU) – The city of Ann Arbor, Michigan, has effectively decriminalized psilocybin or “magic” mushrooms along with other natural psychedelics in the latest sign that public opinion across the U.S. is continuing to turn against prohibitionist policies.

On Monday, the Ann Arbor City Council unanimously voted in favor of a resolution that would make it the city’s lowest-ranked law enforcement priority to the investigate or arrest anyone planting, cultivating, purchasing, transporting, distributing, using or possessing entheogenic plants or plant compounds.

The resolution applies to all psychedelics derived from plants and fungi, including psilocybin mushrooms, ayahuasca, ibogaine, mescaline, peyote and other substances with hallucinogenic properties deemed illegal under state and federal law.

The council also requires the Washtenaw County Prosecutor’s Office to halt the prosecution of those involved in the use of entheogenic plants and plant compounds.

Ann Arbor now joins a growing list of cities including Denver, Colorado, and the California cities of Santa Cruz and Oakland that have decriminalized all entheogenic plants. Other cities including Chicago and Austin are considering similar measures. A ballot measure that would legalize the use of psilocybin in therapeutic settings will also be voted on in the state of Oregon this November.

The move to de-prioritize law enforcement around psychedelics was spearheaded by the efforts of local grassroots advocacy group Decriminalize Nature Ann Arbor, or DNA2.

At the beginning of the year, councilmembers were skeptical about any move to decriminalize psychedelics. Since then, they’ve found themselves convinced by evidence of the therapeutic and spiritual benefits of psychedelics, including for mental health treatment and treating addiction, reports MLive.

Councilmember Zachary Ackerman cited the opening of a $17 million psychedelic and consciousness research center by Johns Hopkins Medicine as proof of “the tremendous potential of these future medicines.” The Center for Psychedelic and Consciousness at Johns Hopkins University in Baltimore is currently conducting clinical trials to find out whether the drug is suitable as a prescription drug for the U.S. market.

Councilmember Jack Eaton described the council’s unanimous backing for the decriminalization resolution as carrying on the city’s legacy of backing the local decriminalization of marijuana during the 1970s, when the plant was still illegal under state and federal law.

The resolution doesn’t allow for the commission of crimes or any significant violation of state or federal law, and any use of entheogenic substances that pose a threat to public health and safety could require intervention by law enforcement bodies.

In the resolution, entheogenic plants are defined as the full spectrum of plants and fungi that contain indole amines, tryptamines and phenethylamines “that can benefit psychological and physical wellness, support and enhance religious and spiritual practices, and can reestablish human’s inalienable and direct relationship to nature.”

The resolution also states that psychedelic substances can be used to address substance abuse problems, addiction, recidivism, trauma, post-traumatic stress, depression, anxiety, grief, cluster headaches and other debilitating conditions.

“The use of entheogenic plants, which can catalyze profound experiences of personal and spiritual growth, have been shown by scientific and clinical studies and traditional practices to be beneficial to the health and well-being of individuals and communities in addressing these conditions,” it states.

Psilocybin mushrooms are currently considered a Schedule 1 narcotic by the Drug Enforcement Agency.

However, psilocybin – the main chemical component of the mushrooms – was designated as a “breakthrough therapy” by the FDA in 2019 due to the positive results of psilocybin in treating depression, anxiety, addiction, and other mental health problems.

Studies have also shown how a microdose of psilocybin—far from the level needed for a full-blown trip—actually increases the creativity and empathy of participants.

Other researchers have also found that psilocybin has provided effective help to patients struggling to quit other addictive substances such as cigarettes.

The newfound recognition of psilocybin therapy as a valid treatment has eroded old stereotypes of psilocybin as some intoxicating and hallucination-inducing party drug that drives its users insane – a reputation that largely grew out of the hippie counterculture of the 1960s when they were widely known as “psychedelic” or “magic” mushrooms.

The resolution further notes that entheogenic plants have been the basis of spiritual practices by human cultures for thousands of years, yet those who seek them for the sake of improving their health and wellbeing must risk arrest and prosecution to obtain them.

“Decriminalization of naturally occurring medicines is necessary for progress,” councilmember Jeff Hayner said in a press release from DNA2 last week, reports Detroit Metro Times. “We can no longer turn a blind eye towards the wisdom of indigenous peoples, and the bounty the earth provides. I have been moved by the testimonies of those who have found profound relief from the use of entheogenic plants.”
