Gene expression changes with meditation With evidence growing that meditation can have beneficial health effects, scientists have sought to understand how these practices physically affect the body. A new study by researchers in Wisconsin, Spain, and France reports the first evidence of specific molecular changes in the body following a period of mindfulness meditation. The study investigated the effects of a day of intensive mindfulness practice in a group of experienced meditators, compared to a group of untrained control subjects who engaged in quiet non-meditative activities. After eight hours of mindfulness practice, the meditators showed a range of genetic and molecular differences, including altered levels of gene-regulating machinery and reduced levels of pro-inflammatory genes, which in turn correlated with faster physical recovery from a stressful situation. The study was published in the journal Psychoneuroendocrinology. The results show a down-regulation of genes that have been implicated in inflammation.
How to Hack Your Mind: Using Biofeedback to Increase Resilience Two important skills for any man, and especially any would-be sheepdog are 1) managing stress 2) and remaining resilient in the face of extreme adversity. In our post about managing stress arousal for optimal performance, we broke down what happens to the body and mind as it deals with increasing levels of stress. Basically, as stress levels rise, our mental and physical performance deteriorates. During my research about developing a sheepdog mentality, I kept coming across reports on how the U.S. military is spending tens of millions of dollars each year researching the vital question of how to make soldiers more resilient. In 2008 the U.S. Besides giving soldiers basic cognitive therapy tools they can use to manage stress, the Department of Defense has also experimented with technology that allows soldiers to monitor their physiological response to it. The real-time monitoring of one’s physiological responses is called biofeedback. Does biofeedback live up to its claims? Nothing.
Neurostimulation: The Next Mind-Expanding Idea Amol Sarva expounds on the next frontier in the exploration of consciousness: neurostimulation (via Wired UK): The idea of stimulating brain performance seemed very plausible when I first heard about it, taking my PhD in cognitive science at Stanford. Your brain operates with electricity; why couldn’t electric current or waves boost it a bit? Gentlemen physicists such as Volta and Galvani were fiddling with frogs’ legs and cadavers back around the late 18th century. Another Italian wrote about curing melancholia with electricity in 1804. And today, everyone knows about the power of shock therapy.But what appeared on my radar in 2003 was different: a headset that sent weak electromagnetic waves into your head.
untitled This is your brain on art: Why we’re moved by certain works Great art is often said to be universal. But when we read, hear, or see a work that strikes a chord within us, the experience feels intensely personal. Although the artist may live on the other side of the world, or even have died centuries ago, he or she seems to be speaking directly to us. So what’s behind this striking sense of connectedness? A trio of brain researchers believes it has found an answer. “Certain artworks, albeit unfamiliar, may be so well-matched to an individual’s unique makeup that they obtain access to the neural substrates concerned with the self—access which other external stimuli do not get,” writes a research team led by Edward Vessel of New York University’s Center for Brain Imaging. This activation allows the poem, play, or painting “to interact with the neural processes related to the self, affect them, and possibly even be incorporated into them,” the researchers write in the journal Frontiers in Neuroscience.
How to (Not) Give a Fuck Like a Zen Master About three months ago, I whimsically typed the above tweet and hurtled it out into the twittersphere for whomever’s wandering eyes might happen upon it. The tweet was basically a passing thought, a random splash from my ceaseless stream of consciousness. But I continued to reflect upon it. And I came to see it as a particularly concise, memorable summary of many of the transformative perspectives I’ve gained through studying Zen and Taoism. On one hand, Zen and Taoism are often popularly summarized as Philosophies of Giving Zero Fucks. No joke: There is actually a great Taoism website called HowToNotGiveAFuck.com. And one time on the Internet I stumbled upon this quote, which is supposedly from the philosopher and countercultural hero, Robert Anton Wilson: “After years of vehement and passionate study of the ideograms of the Tao Te Ching, I think I have summarized it all into a couple of words . . .Fuck it.And if you can’t fuck it, ignore it. “Let life happen to you.
A Neuroscientist's Radical Theory of How Networks Become Conscious - Wired Science WIRED: How do you square what you believe about animal consciousness with how they're used in experiments? Koch: There are two things to put in perspective. First, there are vastly more animals being eaten at McDonald's every day. The number of animals used in research pales in comparison to the number used for flesh. And we need basic brain research to understand the brain's mechanisms. WIRED: Getting back to the theory, is your version of panpsychism truly scientific rather than metaphysical? Koch: In principle, in all sorts of ways. The theory also says you can have simple systems that are conscious, and complex systems that are not. The more relevant question, to me as a scientist, is how can I disprove the theory today. WIRED: I still can't shake the feeling that consciousness arising through integrated information is — arbitrary, somehow. Koch: If you think about any explanation of anything, how far back does it go? With consciousness, it's ultimately going to be like that.
Your brain sees things you don't University of Arizona doctoral degree candidate Jay Sanguinetti has authored a new study, published online in the journal Psychological Science, that indicates that the brain processes and understands visusal input that we may never consciously perceive. The finding challenges currently accepted models about how the brain processes visual information. A doctoral candidate in the UA's Department of Psychology in the College of Science, Sanguinetti showed study participants a series of black silhouettes, some of which contained meaningful, real-world objects hidden in the white spaces on the outsides. Saguinetti worked with his adviser Mary Peterson, a professor of psychology and director of the UA's Cognitive Science Program, and with John Allen, a UA Distinguished Professor of psychology, cognitive science and neuroscience, to monitor subjects' brainwaves with an electroencephalogram, or EEG, while they viewed the objects. The answer, Sanguinetti's data indicates, is yes.
Autonomous sensory meridian response A video intended to trigger ASMR Autonomous sensory meridian response (ASMR) is a euphoric experience characterized by a static-like tingling sensation on the skin that typically begins on the scalp and moves down the back of the neck and upper spine, precipitating relaxation. Overview[edit] Definition[edit] Origins of the name[edit] The term 'autonomous sensory meridian response' (ASMR) was coined on 25 February 2010 by Jennifer Allen, a cybersecurity professional residing in New York[3] in the introduction to a Facebook Group she founded entitled the 'ASMR Group'.[4] Prior to the subsequent social consensus that led to what is now the ubiquitous adoption of that term, other names were proposed and discussed at a number of locations including the Steady Health forum, the 'Society of Sensationalists' Yahoo! Allen chose the words intending or assuming them to have the following specific meanings: The sensation and its triggers[edit] The sensation[edit] The triggers[edit] Whispering triggers[edit]
Herpes Medication Produces "Walking Corpse Syndrome" Pharmacologists have discovered a mechanism that triggers Cotard’s syndrome – the mysterious condition that leaves people feeling like they, or parts of their body, no longer exist. With the ability to switch the so-called walking corpse syndrome on and off comes the prospect of new insights into consciousness.Acyclovir – also known by the brand name Zovirax – is a common drug used to treat cold sores and other herpes infections. However, about 1 per cent of people who take the drug orally or intravenously experience some psychiatric side effects, including Cotard’s. Learning New Ideas Alters Brain Cells Phineas Gage proved that matter could affect consciousness. Now, Shernaz Bamji and Stefano Brigidi of the University of British Columbia have proven the reverse is also true. Looks like the “hardwiring” in our brains isn’t so hard: A new University of British Columbia study identifies an important molecular change that occurs in the brain when we learn and remember.Published this month in Nature Neuroscience, the research shows that learning stimulates our brain cells in a manner that causes a small fatty acid to attach to delta-catenin, a protein in the brain.
Recurring dream A recurring dream is a dream which is experienced repeatedly over a long period. They can be pleasant or nightmarish and unique to the person and their experiences. Common themes in recurring dreams[edit] Through psychological analyses and studies, some recurrent themes have been identified. Difficulties with house maintenanceTeeth falling out - Freud believed that if a woman had a recurring dream of her teeth falling out that she unconsciously longed to have children. The subjects of recurring dreams do vary. Being held down or otherwise unable to move (compare sleep paralysis)Nakedness in a public placeBeing held back in school or failing a testLosing the ability to speakEscaping or being caught in a tornado/stormDrowning, or otherwise not being able to breatheFinding lost itemsUnable to turn on the lights in one's houseBeing with a significant other. Psychological disorders associated with recurring dreams[edit] Possible explanations for recurring dreams[edit] See also[edit]
Brain stimulation affects compliance with social norms Public release date: 3-Oct-2013 [ Print | E-mail Share ] [ Close Window ] Contact: Christian Ruffvchristian.ruff@econ.uzh.ch 41-446-345-067University of Zurich How does the human brain control compliance with social norms? The biological mechanisms that underlie norm compliance are still poorly understood. Prefrontal cortex controls norm behavior For the study, 63 participants took part in an experiment in which they received money and were asked to decide how much of it they wanted to share with an anonymous partner. By means of a technique called "transcranial direct current stimulation," which sends weak and painless electric currents through the skull, the excitability of specific brain regions can be modulated.
