Magnetic resonance imaging (MRI) techniques provide an extremely detailed, 3-D view of a living brain.
Even with my method of trying to become as well-read and to talk to as many people as I can, there are still things about this book that were really hard for someone who’s not a neuroscientist to write.
The problem is even science doesn’t really know all the ways the brain does what it does. When I did the research about how memories actually are formed, I learned that memories are stored in various parts of the brain associated with the initial sensations. When you pull up these bits of memory from random access in your brain, they get stuck to other things you associate with them. By golly, I read that and I [was] stunned at how easy it is to either remember things that you think you knew, but remember them wrongly, or to have someone suggest something to you and that screws you up. If it’s true that these illusions are evidence that the brain is filling in gaps to make nice seamless narratives, then the brain is actively constructing reality.
This research has important sociological implications and it would be important to to look at theory regarding the social construction of reality.

Two years after being discovered deep in a South African cave, the 1,500 fossils excavated during the Rising Star Expedition have been identified as belonging to a previously unknown early human relative that National Geographic Explorer-in-Residence Lee Berger and team have named Homo naledi.
With at least 15 individuals of all ages and both sexes represented, the find adds an unprecedented amount of information to our understanding of early human evolution in Africa. In addition, the absence of any other animal remains or large debris in the fossil chamber strongly suggests that these non-human beings intentionally deposited their dead within this cave.

Check the flow: Brain regions associated with innovative performance light up during improvisation. Researchers in voice, speech, and language studied the brain activity of freestyling rappers using functional magnetic resonance imaging (fMRIs).
Siyuan Liu, Allen Braun, and a team of neuroscientists affiliated with the National Institute of Deafness and Other Communication Disorders (NIDCD) at the National Institutes of Health (NIH) published their findings online in the latest issue of Scientific Reports. Twelve freestyle artists, all with at least 5 years rapping experience, participated in the study and had their brains scanned while performing two different musical tasks. The findings showed that freestyling changes activity in the prefrontal cortex, the brain region associated with language and decision-making. Other parts of the brain saw increased activity as well during the freestyle portion of the experiment. The team’s research will continue to explore more linguistic art forms—like poetry and storytelling—as well as other phases of the creative process. As their work continues, the researchers are hopeful that they can offer more insights into what happens in the brain after the initial burst of inspiration strikes. I get what you mean evelyn, I just wish I could get lottery numbers, but jokes aside I get what you are talking about and yes the brain is amazing.

Within sight of downtown Seoul, capital of South Korea and a hub of stressful modern life, salesman Sungvin Hong rests after a hike in Bukhansan National Park. When you head out to the desert, David Strayer is the kind of man you want behind the wheel. While the enchiladas are cooking, Strayer’s graduate students tuck my head into a sort of bathing cap with 12 electrodes embedded in it. In 1865 the great landscape architect Frederick Law Olmsted looked out over the Yosemite Valley and saw a place worth saving. In England researchers from the University of Exeter Medical School recently analyzed mental health data from 10,000 city dwellers and used high-resolution mapping to track where the subjects had lived over 18 years.
All this evidence for the benefits of nature is pouring in at a time when disconnection from it is pervasive, says Lisa Nisbet, a psychology professor at Canada’s Trent University. Nooshin Razani at UCSF Benioff Children’s Hospital in Oakland, California, is one of several doctors who have noticed the emerging data on nature and health.
After two years living in the wild, engineer Matthew Sakae Forkin is back in the San Francisco area. Perhaps no one has embraced the medicalization of nature with more enthusiasm than the South Koreans. At the Twin Oaks Communities Conference in Louisa, Virginia, where people from around the world come to talk about eco-villages, cooperative housing, and how to live closer to nature, a conference attendee immerses herself in the communal mud pit. Saneum is one of three official healing forests in South Korea, but 34 more are planned by 2017, meaning most major towns will be near one. Korea Forest Service scientists used to study timber yields; now they also distill essential oils from trees such as the hinoki cypress and study them for their ability to reduce stress hormones and asthma symptoms.


A lot of different things, judging from the neuroscience research that’s starting to come in. Delaney Doyle holds edible daylilies she picked from her family’s land in the mountains of eastern Kentucky. A few years ago, for example, in an experiment similar to Bratman’s, Stephen Kaplan and his colleagues found that a 50-minute walk in an arboretum improved executive attention skills, such as short-term memory, while walking along a city street did not. Photographer Lucas Foglia grew up on a family farm in New York and currently lives in San Francisco.
The technique is critical for identifying abnormalities such as tumors, spotting the warning signs of some brain diseases, and revealing the extent of trauma from strokes.
The book and show both make you the test subject in an array of astonishing challenges and experiments. So the color is stored one place and the sound is stored one place, and the associations are stored throughout.
And  if that’s true, then my constructed reality is valid for me but it may be different than your constructed reality which is valid for you. Maybe from now on, I’ll creat my own world and be extremely happy and free with it, also ignore what people tell or teach me about the world (actually their world).

When an artist easily improvises on the spot, coming up with smooth lyrics and effortless rhymes that flow to the beat in real time, it makes you wonder what amazing things are going on in that brain. They found that when a person spontaneously creates rhyming lyrics, the brain turns up certain regions while turning down others. The improvisation increases activity in the area responsible for thought and action but decreases it in the parts that control and suppress. The perisylvian system (associated with language), the amygdala (linked to emotion), and the cingulate motor areas (motion) were all more engaged, which suggests that spontaneous, creativity involves a unique neural network that links language, mood, movement, and motivation together.
When you are freestyling you must not try to find the right words, but actually allow them to appear to you. Motivated by large-scale public health problems such as obesity, depression, and pervasive nearsightedness, all clearly associated with time spent indoors, Strayer and other scientists are looking with renewed interest at how nature affects our brains and bodies. They found that people living near more green space reported less mental distress, even after adjusting for income, education, and employment (all of which are also correlated with health). Swedish researcher Matilda van den Bosch stresses her subjects with a math test and a simulated job interview. Compared with people who have lousy window views, those who can see trees and grass have been shown to recover faster in hospitals, perform better in school, and even display less violent behavior in neighborhoods where it’s common. A real-life experiment is under way at the Snake River Correctional Institution in eastern Oregon. Japanese researchers led by Yoshifumi Miyazaki at Chiba University sent 84 subjects to stroll in seven different forests, while the same number of volunteers walked around city centers.
We love our state and national parks, but per capita visits have been declining since the dawn of email.
As part of a pilot project, she’s training pediatricians in the outpatient clinic to write prescriptions for young patients and their families to visit nearby parks.
In Finland, a country that struggles with high rates of depression, alcoholism, and suicide, government-funded researchers asked thousands of people to rate their moods and stress levels after visiting both natural and urban areas. It’s autumn, and the changing foliage and crisp air have lured scores of urban refugees to the woods.
In the new industrial city of Deajun, I pay a visit to the forest minister, Shin Won Sop, a social scientist who has studied the effects of forest therapy on alcoholics. Korean researchers used functional MRI to watch brain activity in people viewing different images.
Stanford researcher Greg Bratman and his colleagues scanned the brains of 38 volunteers before and after they walked for 90 minutes, either in a large park or on a busy street in downtown Palo Alto.
His research builds on the attention restoration theory proposed by environmental psychologists Stephen and Rachel Kaplan at the University of Michigan. The colorful graph charted the power of my brain waves at a range of frequencies and compared them with samples from the two groups that had stayed in the city.
But even if the study bears it out, it won’t offer anything like a full explanation of the brain-on-nature experience. Here, Sweeney discusses some of the book’s most surprising optical illusions, and how learning the inner workings of the brain has made him a happier person. All of a sudden if one color on one cone starts firing differently than it did a moment before, you can have this illusion of movement as the color changes and shifts from cone to cone to cone to cone. Except they just got to the point quicker, by realizing that what we see is an illusion, and the mind is an auditory illusion of sound.
Howley, you will like my photo of a sunflower with the Fraser’s optical illusion on it!! They toured the desert islands off the southeastern coast of the Baja Peninsula and they listened to presentations by more than a dozen experts, including several whose Baja California research is funded by the Society.
As the brain activity shifts, the results showed that a unique neural network activates, suggesting that there are distinct pathways for improvisational creativity. The findings suggest that the flowing, freestyling brain can relax its neural constraints to allow freer oral expression of words and ideas.
As creativity stems from the unconcious, limiting directed conciousness is the key; time seems to be meaningless when emmersed in a freestyle.


When we slow down, stop the busywork, and take in beautiful natural surroundings, not only do we feel restored, but our mental performance improves too. He’ll compare our brain waves with those of similar volunteers who are sitting in a lab or hanging out at a parking lot in downtown Salt Lake City. Wires sprouting from them will send my brain’s electrical signals to a recorder for later analysis. Olmsted had already designed Central Park in New York City; he was convinced that beautiful green spaces should exist for all people to enjoy.
It went back at least to Cyrus the Great, who some 2,500 years ago built gardens for relaxation in the busy capital of Persia.
Building on advances in neuroscience and psychology, they’ve begun to quantify what once seemed divine and mysterious. When she delivers them into a virtual forest with singing birds, their heart rate soon recovers its normal rhythm.
The forest walkers hit a relaxation jackpot: Overall they showed a 16 percent decrease in the stress hormone cortisol, a 2 percent drop in blood pressure, and a 4 percent drop in heart rate. More than 70 percent say their jobs, which require notoriously long hours, make them depressed, according to a survey by electronics giant Samsung. What’s still needed, he says, is better data on specific diseases and on the natural qualities that make a difference. Strayer’s students seem more relaxed and sociable than they do in the classroom, he says, and they give much better presentations.
When the volunteers were looking at urban scenes, their brains showed more blood flow in the amygdala, which processes fear and anxiety. But scientific evidence indicates that even a trip to the backyard or a city park provides health and psychological benefits. My theta signals were indeed lower than theirs; the soft fascination of the San Juan River had apparently quieted my prefrontal cortex, at least for a while. Something mysterious will always remain, Strayer says, and maybe that’s as it should be.
So in this dream we’re experiencing, it is in fact life that chose us, and life that manifests energy that is within us. For the second part, they all performed a set of lyrics they already knew to the same beat.
I am usually very focused on my word choice, so I tend to think forward and backward, so to speak. A cognitive psychologist at the University of Utah who specializes in attention, Strayer knows our brains are prone to mistakes, especially when we’re multitasking and dodging distractions. Strayer has demonstrated as much with a group of Outward Bound participants, who performed 50 percent better on creative problem-solving tasks after three days of wilderness backpacking. Feeling like a beached sea urchin, I walk carefully to a grassy bank along the San Juan River for ten minutes of restful contemplation. And in 2015 an international team overlaid health questionnaire responses from more than 31,000 Toronto residents onto a map of the city, block by block. Miyazaki believes our bodies relax in pleasant, natural surroundings because they evolved there. One recent Nature Conservancy poll found that only about 10 percent of American teens spend time outside every day.
To guide the physicians and patients into a new mind-set, she says, “we have transformed the clinical space so nature is everywhere.
Forty middle-aged firefighters who have been diagnosed with post-traumatic stress disorder are paired off on the platforms as part of a free three-day program sponsored by the local government. In contrast, the natural scenes lit up the anterior cingulate and the insula—areas associated with empathy and altruism. Bratman believes that being outside in a pleasant environment (not the kind where you’re getting eaten alive by gnats or pummeled by hail) takes us outside of ourselves in a good way. Ask any artist, whether painters, poets or craftsmen all will attribute a lessening of directed consciousness. Among other things, his research has shown that using a cell phone impairs most drivers as much as drinking alcohol does.
The three-day effect, he says, is a kind of cleaning of the mental windshield that occurs when we’ve been immersed in nature long enough.
I’m supposed to think of nothing in particular, just watch the wide, sparkling river flow gently by. Along with Olmsted, they built the spiritual and emotional case for creating the world’s first national parks by claiming that nature had healing powers. Those living on blocks with more trees showed a boost in heart and metabolic health equivalent to what one would experience from a $20,000 gain in income.
That’s what Richard Mitchell, an epidemiologist at the University of Glasgow in Scotland, thought at first.
Our senses are adapted to interpret in- formation about plants and streams, he says, not traffic and high-rises. According to research by the Harvard School of Public Health, American adults spend less time outdoors than they do inside vehicles—less than 5 percent of their day. In North America groups of men in the woods likely would be hunting or fishing, but here, after a morning of hiking, they practice partner yoga, rub lavender massage oil into each other’s forearms, and make delicate dried flower collages.
A hundred-million-dollar healing complex is under construction next to Sobaeksan National Park.
Lower mortality and fewer stress hormones circulating in the blood have also been connected to living close to green space.
For some reason I view my freestyle performance (which is done with a live band, rather than an instrumental track) as a reflection of how my brain is working.
Moreover, the lowest income people seemed to gain the most: In the city, Mitchell found, being close to nature is a social leveler.
