    A Look at Nootropics

    In general, people will always want to improve themselves whether it is by becoming faster, smarter, fitter or in any other capacity. Because of that, many products are released on a yearly basis that claim to improve these aspects. One that is new to many are Nootropics, which has quickly become popular among those looking to boost their mental performance.

    Becoming popular in this specific market is quite an accomplishment because the entire market was valued at $2.3 billion in 2015 and is set to be worth between $11 and $12 billion by 2024. Even with their growing popularity, people are still not adequately educated on the background of Nootropics and their benefits. By taking time to study Nootropics, you may be able to see why  many are interested in the way they may be able to work to improve mental acuity which has influence over many unique areas of life.



    What Are Nootropics?

    Nootropics come in a variety of different forms including caffeine, prescription medication, and supplements.  Nootropics are used by people who wish to improve various aspects of their cognitive function. Due to the numerous ways Nootropics work, they are being used by people for a number of reasons.  For example, students are interested in them to help study and in  business people are interested in how they may help focus on their work responsibilities. In addition, Nootropics are used by the medical industry for ADD and ADHD.

    Over the past few years, “Nootropics” has been known by a number of different names including smart and limitless pills.  

    However, they have become increasingly popular among people looking to boost cognitive function over short and long periods of time.

    The Benefits of Nootropics

    Aside from treating specific disorders, there are a host of potential benefits of Nootropics, which is why popularity has spread so much over recent years.


    1. Focus

    One of the key reasons people take Nootropics is to help with focus. Similar to coffee, they can stimulate alertness. Because of that, many people have reported a faster and more in-depth learning ability than they did prior to taking a Nootropic.

    1. Mood Enhancer

    While this may apply to only specific types of Nootropics, many take Nootropics because they are looking for ways to try and enhance their mood and reduce anxiety.

          3.  Increased Energy Levels

    Similar to the effects of caffeine, Nootropics are often taken by people who want to increase mental energy levels for concentration at task.

         4. Reasoning & Problem Solving

    There is an even smaller subset of Nootropics that people take especially for influencing reasoning and general problem-solving skills and complex task.

    .

    The Side Effects of Nootropics

    Side effects do not affect the majority of users but should be given consideration before use, and when in doubt people should consult their health professional on whether or not a Nootropic may be right for them.  Underlying health conditions might play a factor in whether or not side effects may result from taking Nootropics.

     


    With the potnetial benefits Nootropics may offer, it is easy to see why Nootropics have become popular among those looking to increase cognitive performance in their everyday activities.

    Too much structured knowledge hurts creativity, study shows

    Structure organizes human activities and help us understand the world with less effort, but it can be the killer of creativity, concludes a study from the University of Toronto's Rotman School of Management.

    While most management research has supported the idea that giving structure to information makes it easier to cope with its complexity and boosts efficiency, the paper says that comes as a double-edged sword.

    "A hierarchically organized information structure may also have a dark side," warns Yeun Joon Kim, a PhD student who co-authored the paper with Chen-Bo Zhong, an associate professor of organizational behaviour and human resource management at the Rotman School.

    The researchers showed in a series of experiments that participants displayed less creativity and cognitive flexibility when asked to complete tasks using categorized sets of information, compared to those asked to work with items that were not ordered in any special way. Those in the organized information group also spent less time on their tasks, suggesting reduced persistence, a key ingredient for creativity.

    The researchers ran three experiments. In two, study participants were presented with a group of nouns that were either organized into neat categories or not, and then told to make as many sentences as they could with them.

    The third experiment used LEGO® bricks. Participants were asked to make an alien out of a box of bricks organized by colour and shape or, in a scenario familiar to many parents, out of a box of unorganized bricks. Participants in the organized category were prohibited from dumping the bricks out onto a table.

    The findings may have application for leaders of multi-disciplinary teams, which tend to show inconsistent rates of innovation, perhaps because team members may continue to organize their ideas according to functional similarity, area of their expertise, or discipline.

    "We suggest people put their ideas randomly on a white board and then think about some of their connections," says Kim. Our tendency to categorize information rather than efficiency itself is what those working in creative industries need to be most on guard about, the researchers say.

    Brain waves may focus attention and keep information flowing

    Studies suggest the oscillations created by nerve cell activity have roles of their own.

    We can’t see it, but brains hum with electrical activity. Brain waves created by the coordinated firing of huge collections of nerve cells pinball around the brain. The waves can ricochet from the front of the brain to the back, or from deep structures all the way to the scalp and then back again.

    Called neuronal oscillations, these signals are known to accompany certain mental states. Quiet alpha waves ripple soothingly across the brains of meditating monks. Beta waves rise and fall during intense conversational turns. Fast gamma waves accompany sharp insights. Sluggish delta rhythms lull deep sleepers, while dreamers shift into slightly quicker theta rhythms.

    Researchers have long argued over whether these waves have purpose, and what those purposes might be. Some scientists see waves as inevitable but useless by-products of the signals that really matter — messages sent by individual nerve cells. Waves are simply a consequence of collective neural behavior, and nothing more, that view holds. But a growing body of evidence suggests just the opposite: Instead of by-products of important signals, brain waves are key to how the brain operates, routing information among far-flung brain regions that need to work together.

    MIT’s Earl Miller is among the neuro­scientists amassing evidence that waves are an essential part of how the brain operates. Brain oscillations deftly route information in a way that allows the brain to choose which signals in the world to pay attention to and which to ignore, his recent studies suggest.

    Other research supports this view, too. Studies on people with electrodes implanted in their brains suggest brain waves, and their interactions, help enable emotion, language, vision and more.

    When these waves are abnormal, brainpower suffers, studies find. Detailed looks at how the brain uses these waves raise the possibility of tweaking the signals with electrical nudges — interventions that could lead to therapies that can correct memory problems and mental illness, for instance. Already, early attempts have led to improvements in people’s memory.

    Types of brain waves

    Scientists are studying how oscillations generated by nerve cells affect brain function. Although the boundaries between different wave types can be fuzzy, these oscillations can be grouped by frequency.

    Fast gamma waves have been linked to states of high attention. 30 to 80 Hz

     

    Beta waves may be involved in movement and complex tasks such as memory and decision making.  12 to 30 Hz

     

    The first neuronal oscillations discovered, alphawaves appear when a relaxed person closes his eyes. 8 to 12 Hz

     

    Theta oscillations may help the brain sort information essential for navigation. 4 to 8 Hz

     

    Slow delta waves mark deep sleep and anesthesia. 1.5 to 4 Hz

     

    C. CHANG

    These insights about brain waves coincide with a shift in neuroscience away from a view that reduces the brain down to the behavior of single nerve cells, or neurons. That’s like thinking of the brain as “a giant clock, and if you figure out each gear, you’ll figure out the brain,” Miller says. But “it’s not just individual neurons in a giant clock. It’s networks interacting in a very dynamic, fluid way.”

    Central to those interactions, Miller and others think, are coordinated brain waves. “The oscillations are the most powerful signal in the brain,” Miller says. “How could evolution not have taken advantage of that?”

    In three recent papers, Miller and colleagues argue that two different types of brain waves — beta and gamma — work together to selectively choose the information that makes it into working memory. Gamma waves that cycle 30 to 80 times per second (30 to 80 hertz) help coordinate information streaming in from our senses — what we feel, see and smell. In contrast, slower 12 to 30 Hz beta waves are the messages that help keep us on task by guiding the brain toward the sensory signals worth paying attention to.

    These two types of brain oscillations engage in a neural seesaw: When beta waves are strong, akin to a stereo blasting, gamma waves are weak, as if the volume had been dialed down, and vice versa. Miller and colleagues saw this push-and-pull action in the brains of monkeys with implanted electrodes as the animals completed a tricky memory task, one that required the monkeys to hold several pieces of information in their minds at the same time. The results were described January 26 in Nature Communications. “At all these complex decision points, you can see the beta and gamma doing this complex dance in a way that you’d expect if they’re controlling working memory,” Miller says.

    These two types of waves were generated in different parts of the brain, offering spatial clues about how the brain focuses itself, the researchers also found. Sensory information, organized by gamma waves, skims the superficial layers of the brain, experiments on monkeys showed. But slower, more goal-directed waves, a mix of alpha and beta waves, are deeper in the brain. And those slower, deeper waves could actually dial down the strength of the gamma waves that rippled along the outer brain. The deeper waves were selecting which sensory information to pay attention to, the researchers proposed in the Jan. 30 Proceedings of the National Academy of Sciences.

    A third paper, in the Feb. 7 Neuron, shows similar interactions between gamma and beta waves while monkeys matched patterns of dots on a computer screen. Some of the patterns were clearly different but still belonged to the same category, an easy task akin to knowing that both a dog and a cat are types of animals. Other times, the patterns were harder to classify and required more sophisticated mental work, similar to knowing that trains and bicycles are both types of transportation. Gamma waves were present when the monkeys were puzzling out an easy category. But when higher-level categorization was required, beta waves started to roll.  

    These interactions between gamma and beta waves might be how the brain solves an information overload problem, Miller suspects. Incoming sensory input constantly bombards the brain, and much of it is meaningless. The brain needs a way to figure out if it should ignore the feeling of a scratchy shirt, but pay attention to the ringing phone. These two rhythms may offer a way for “volitional control over what you think about,” Miller says, allowing a person to consciously choose what information to bring to mind. 

    Oscillations may also shape visual information as it travels through the brain, says Charles Schroeder, a neuroscientist at the Nathan S. Kline Institute for Psychiatric Research in Orangeburg, N.Y. He and colleagues are studying a different ebb and flow of oscillations from the one Miller recently described. This one probably involves a host of different kinds of waves, including theta waves, and happens in the split second when your eyes dwell on a scene — a pause that usually lasts about 200 milliseconds.

    When you look at a scene, the first half of the time it takes to stare is spent on visual information streaming into your brain. But toward the end of that fixation time, “the information flow reverses,” Schroeder says. Different neuronal oscillations carry signals from the brain’s command center, ready to direct the eyes to the next spot. “Literally within a tenth of a second before you move your eyes, there is this incredible flash of network activity in the front of the brain, and then the eyes move,” Schroeder says. “It’s really a dramatic thing.” Schroeder and colleagues have caught this action in monkeys’ brains, and more recently, in people implanted with electrodes as part of epilepsy treatment.

    But some vision researchers still dismiss these oscillations as noise, convinced that the activity of single neurons — and not the collective waves that result from that activity — is the key to understanding the brain, Schroeder says. “It’s still difficult to convince people that brain oscillations are functional.”

    Researchers may argue over the function of brain waves for years to come, says neuroscientist and neurologist Robert Knight of the University of California, Berkeley. He believes that information, at its core, is held in the signals zipped off by neurons. But work from his lab has convinced him that oscillations help those signals reach the right spot, connecting brain areas in important ways. “You’ve got to have a way to get brain areas communicating,” he says. “What oscillations do is provide a routing mechanism.”

    And oscillations do this quickly, he says. Human brains are incredibly fast. “We’re handling massive amounts of information in subsecond time periods,” Knight says. “And you have to have some way to shape it, to control it.” Waves, he says, give the brain a way to tune out extraneous information by temporarily shutting down unnecessary communication lines.

    Knight and colleagues recently spotted fast gamma waves at work as people did a wide range of tasks, including repeating words, answering questions about themselves and distinguishing male faces from female. A certain gamma wave pattern seemed to predict when people would get the right answer on these tasks, the team reported in December 2017 in Nature Human Behavior. Gamma waves, the team suspects, link up areas of the brain that are needed to turn goals into action.

    If oscillations are crucial information routers in the brain, then changing them might be beneficial when information is distorted or lost. Altered oscillations have been observed in disorders such as autism, Parkinson’s disease, depression and anxiety, and even in normal aging.

    A study published February 6 in Nature Communications hints at the potential of tweaking these rhythms. Youssef Ezzyat, a neuroscientist at the University of Pennsylvania, and colleagues studied memory abilities in 25 people who had electrodes implanted in their brains as part of their epilepsy treatment.

    As the researchers gave the people lists of words to remember, electrodes monitored neural oscillations. A computer algorithm then figured out which assortment of brain waves indicated when a person was likely to remember the word, an assortment that varied slightly from person to person.

    When those good performance signals were missing, the researchers delivered a short burst of electricity to the brain — “a bit of a nudge to course correct,” Ezzyat says. And these nudges improved performance.

    Specifically manipulating brain waves to treat brains is a long way off, Ezzyat cautions. But he and colleagues are making progress. In the meantime, his results and others’ are powerful signs that brain waves aren’t just an idle hum.

    The Simple Reason Exercise Enhances Your Brain

    Evidence keeps mounting that exercise is good for the brain. It can lower a person's risk for Alzheimer's disease and may even slow brain aging by about 10 years. Now, new research helps illuminate how, exactly, working out improves brain health.

    In one research review published in the British Journal of Sports Medicine, researchers examined 39 studies that looked at the link between exercise and cognitive abilities among people over age 50. They found that aerobic exercise appears to improve a person’s cognitive function and resistance training can enhance a person’s executive function and memory. Other exercises like tai chi were also linked to improvements in cognition, though there wasn’t as much available evidence. Ultimately, the researchers concluded that 45 minutes to an hour of moderate-to-vigorous exercise was good for the brain.

    “There is now a wide body of research showing that the benefits to the body with exercise also exist for the brain,” says study author Joe Northey, a PhD candidate at the University of Canberra Research Institute for Sport and Exercise in Australia. “When older adults undertake aerobic or resistance exercise, we see changes to the structure and function of areas of the brain responsible for complex mental tasks and memory function.”

    But how does exercise have these effects? Another new study presented at the American Physiological Society’s annual meeting in Chicago explored one possible way. In the study, researchers from New Mexico Highlands University found that when people walk, the pressure of making impact with the ground sends waves through the arteries, which increase blood flow to the brain (also called cerebral blood flow). Getting enough blood to the brain is important for healthy brain function, since blood flow brings the brain oxygen and nutrients.

    In the small study—which has not yet been published—researchers used ultrasounds to assess arteries and changes in cerebral blood flow in 12 healthy young adults while they were standing, walking and running. The increases in blood flow were greater when the men and women ran, but walking was enough to spur the effect. “[Increased cerebral blood flow] gives the brain more to work with,” says study author Ernest R. Greene, a professor of engineering and biology at New Mexico Highlands University. “It’s another positive aspect of exercise.”

    Scientists are still exploring multiple ways by which fitness improves the brain. But blood flow is a promising path, since it can also help create new brain cells. The protein BDNF (brain-derived neurotrophic factor) also seems to play a role because it helps repair and protect brain cells from degeneration. Exercise can also boost mood by triggering the release of feel-good hormones and chemicals, like endorphins, which can improve brain health. A 2015 study found that exercise may be able to prevent the onset of depressive symptoms. 

    “Each type of exercise seems to have different effects on the growth factors responsible for the growth of new neurons and blood vessels in the brain,” says Northey. “That may indicate why doing both aerobic and resistance training is of benefit to cognitive function.”
