How to Rewire Your Brain For Success
What's the Big Idea?
Until the 1980s, the scientific consensus was that the nervous system was fixed and incapable of regeneration. Growth of neurons was considered most active during prenatal development. As we age, neurons atrophy, the thinking went. Now scientists believe new neurons are continually born throughout adulthood.
Several breakthrough studies suggest that we may have more control over how our brains function and develop throughout adulthood—our thoughts, behaviors, and emotions—than previously assumed.
Why does this matter? Because by learning how to control our mentality, we may be able to deliberately reshape our neural pathways and rewire our brains to make ourselves more successful and fulfilled. In other words, shape your brain and you can shape your life.
Practice and Thinking Rewire the Brain
In 2007, Harvard Medical School conducted a study with volunteers in a lab who were asked to learn and practice a five-finger piano exercise. A neuroscientist instructed half of the volunteers to play as fluidly as they could, trying to keep to the metronome's 60 beats per minute, two hours a day for five days. The other half were instructed to merely think about practicing the piano, holding their hands still while playing the music in their heads. At the end of the five days, both groups underwent a transcranial-magnetic-stimulation test, which enabled scientists to infer the function of neurons.
The test results showed that in both groups, the stretch of motor cortex devoted to these finger movements took over surrounding areas. The finding was in line with a growing number of discoveries showing that greater use of a particular muscle causes the brain to devote more cortical growth to it. Practice rewires the brain. More startling, however, was that the same region of the brain had expanded in the volunteers who merely thought about playing in a disciplined way.
There are two big implications here: 1.) that mental training may have the power to change the physical structure of the brain, and 2.) that the brain doesn't distinguish between a real or imagined exercise.
The Downside of Neuroplasticity
In neuroscience, the previous prevailing belief had been that the adult human brain is essentially "hardwired," so that by the time we reach adulthood we are stuck with what we have. Now we understand that the adult brain retains impressive powers of "neuroplasticity"—the ability to change its structure and function in response to experiences real or imagined.
The downside of neuroplasticity is that negative experiences can have a deleterious effect on our brains. Robert Sapolsky, a professor of neuroendocrinology at Stanford University, has shown that stress is associated with neural degeneration. His research found that long-term stressful life experiences cause elevated production of cortisol, which results in the shrinking of the hippocampus area of the brain. The hippocampus is one of the few regions of the brain known to be able to produce new neurons, a process called neurogenesis.
What's the Significance?
How to Apply These Concepts in Business
We can use these new findings about the brain to help us become better performers at work, more successful in our business dealings, and more fulfilled professionally. By consistently training our thoughts, like those imaginary piano players, we can expand the number of branches and synaptic connections in our hippocampus, potentially leading to an increased ability to retain new information and adapt to new situations. Here are a few practical ways to apply these concepts.
Control your environment.
Because our brain cannot distinguish between real and imagined practice, if we subject ourselves to 30 minutes of watching sensationalized news stories, or find ourselves listening to a 30-minute dose of complaining and gossiping with those people around us, the effect on the brain is the same as if we had lived those experiences ourselves. The good news, according to Sapolsky, is that the negative effects of excessive stress can not only be stopped, but also reversed “once the source, psychological or physical, is removed or sufficiently reduced.” Limit your exposure to negativity by staying away from people, environments, and sources that are negative.
Resist the urge to use self-defeating language. We've all experienced a colleague saying, "You look tired." All the air goes out of our sails and suddenly we feel tired and depleted as we respond, "Yeah, I guess I've been under a lot of stress lately." We do the same thing to ourselves. If you don't feel well, never say it aloud to anyone. Instead, say, "I could use more energy." Also avoid the use of limiting words. Never say cannot when referring to yourself. Instead, reach for a higher-energy statement such as "When I can…" Other limiting words include hopefully, perhaps, one day, and maybe.
Begin and end all communications positively. Today this is especially important when using electronic media, as your messages live in cyberspace forever and continue to define you. It's imperative that the last thing you type is a positive word leading to positive thoughts. Try "Cheers" or "Best" or "Keep smiling." Your brain reaps the benefit of this positive thought, and the recipient gets an upbeat impression of you. It's a twofer.
Begin and end your day positively. Before you go to sleep at night, thank yourself for a great day. When you wake up, the first words in your head should be something like, "I feel absolutely fantastic, glad to be alive. I know today will be successful for me."
Make use of superlatives. In business, we are supposed to be subdued. But when someone asks you how you are, notice the difference between saying, "I'm fine," and "I feel absolutely amazing and vibrantly healthy." Using superlatives bumps your energy to a higher level.
Think bigger than what you actually desire. If all you really want is to land a specific client, by setting this as your intention and thinking of it every day, you will no doubt get it. But if you set your intentions much larger than your core desire—say, to acquire ten new significant clients this year—you trigger several positive psychological benefits. As you daydream and imagine a larger scenario, your core desire starts to feel easy and much more attainable.
A simple way to apply the science of neurogenesis is to be conscious and consistent in thinking positive, proactive thoughts—about your potential, your dreams, your goals, and your achievements. Taking control of your thoughts in this way will help you actually become that accomplished, positive person.
In his new book, Three Simple Steps: A Map to Success in Business and Life (BenBella, 2012) , Trevor Blake outlines recent evidence for neuroplasticity and offers several ways to defend oneself against effects of negative stimuli in our everyday environment.

How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>
Sexuality dilemmas<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>
Regulating designer babies<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>
The father of all giant sea bugs was recently discovered off the coast of Java.
- A new species of isopod with a resemblance to a certain Sith lord was just discovered.
- It is the first known giant isopod from the Indian Ocean.
- The finding extends the list of giant isopods even further.
The ocean depths are home to many creatures that some consider to be unnatural.<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzU2NzY4My9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTYxNTUwMzg0NX0.BTK3zVeXxoduyvXfsvp4QH40_9POsrgca_W5CQpjVtw/img.png?width=980" id="b6fb0" class="rm-shortcode" data-rm-shortcode-id="2739ec50d9f9a3bd0058f937b6d447ac" data-rm-shortcode-name="rebelmouse-image" data-width="1512" data-height="2224" />

We look back at a year ravaged by a global pandemic, economic downturn, political turmoil and the ever-worsening climate crisis.
Billions are at risk of missing out on the digital leap forward, as growing disparities challenge the social fabric.

A new study explains how a chaotic region just outside a black hole's event horizon might provide a virtually endless supply of energy.
- In 1969, the physicist Roger Penrose first proposed a way in which it might be possible to extract energy from a black hole.
- A new study builds upon similar ideas to describe how chaotic magnetic activity in the ergosphere of a black hole may produce vast amounts of energy, which could potentially be harvested.
- The findings suggest that, in the very distant future, it may be possible for a civilization to survive by harnessing the energy of a black hole rather than a star.
The ergosphere<p>The ergosphere is a region just outside a black hole's event horizon, the boundary of a black hole beyond which nothing, not even light, can escape. But light and matter just outside the event horizon, in the ergosphere, would also be affected by the immense gravity of the black hole. Objects in this zone would spin in the same direction as the black hole at incredibly fast speeds, similar to objects floating around the center of a whirlpool.</p><p>The Penrose process states, in simple terms, that an object could enter the ergosphere and break into two pieces. One piece would head toward the event horizon, swallowed by the black hole. But if the other piece managed to escape the ergosphere, it could emerge with more energy than it entered with.</p><p>The movie "Interstellar" provides an example of the Penrose process. Facing a fuel shortage on a deep-space mission, the crew makes a last-ditch effort to return home by entering the ergosphere of a blackhole, ditching part of their spacecraft, and "slingshotting" away from the black hole with vast amounts of energy.</p><p>In a recent study published in the American Physical Society's <a href="https://journals.aps.org/prd/abstract/10.1103/PhysRevD.103.023014" target="_blank" style="">Physical Review D</a><em>, </em>physicists Luca Comisso and Felipe A. Asenjo used similar ideas to describe another way energy could be extracted from a black hole. The idea centers on the magnetic fields of black holes.</p><p style="margin-left: 20px;">"Black holes are commonly surrounded by a hot 'soup' of plasma particles that carry a magnetic field," Comisso, a research scientist at Columbia University and lead study author, told <a href="https://news.columbia.edu/energy-particles-magnetic-fields-black-holes" target="_blank" rel="noopener noreferrer">Columbia News</a>.</p>
Event Horizon Telescope Collaboration<p>While there might not be immediate applications for the theory, it could help scientists better understand and observe black holes. On an abstract level, the findings may expand the limits of what scientists imagine is possible in deep space.</p><p style="margin-left: 20px;">"Thousands or millions of years from now, humanity might be able to survive around a black hole without harnessing energy from stars," Comisso said. "It is essentially a technological problem. If we look at the physics, there is nothing that prevents it."</p>
A popular and longstanding wave of thought in psychology and psychotherapy is that diagnosis is not relevant for practitioners in those fields.
