Do Psychedelics Expand the Mind by Reducing Brain Activity? What would you see if you could look inside a hallucinating brain?

Do Psychedelics Expand the Mind by Reducing Brain Activity?

Despite decades of scientific investigation, we still lack a clear understanding of how hallucinogenic drugs such as LSD (lysergic acid diethylamide), mescaline, and psilocybin (the main active ingredient in magic mushrooms) work in the brain. Is the brain the centre of your universe? The Observer has a fantastic debate between neuroscientists David Eagleman and Raymond Tallis about how much brain science tells us about free will and the unconscious.

Is the brain the centre of your universe?

It’s a wonderful pairing as Eagleman is a broad-thinking wonderboy of neuroscience while Tallis is a veteran street-fighter of brain debates. The main point of contention revlves around whether we can understand the brain as the source of human nature or whether we have to look beyond the individual to make sense of our experience and behaviour. Eagleman: It is clear at this point that we are irrevocably tied to the 3lb of strange computational material found within our skulls. The brain is utterly alien to us, and yet our personalities, hopes, fears and aspirations all depend on the integrity of this biological tissue. How do we know this? As an accompaniment to the piece, I also wrote a ‘brief guide to neuroscience’ that you can also read online.

The Science and History of Treating Depression. Changing Brains for the Better: Article Documents Benefits of Multiple Practices. Practices like physical exercise, certain forms of psychological counseling and meditation can all change brains for the better, and these changes can be measured with the tools of modern neuroscience, according to a review article now online at Nature Neuroscience.

Changing Brains for the Better: Article Documents Benefits of Multiple Practices

The study reflects a major transition in the focus of neuroscience from disease to well being, says first author Richard Davidson, professor of psychology at University of Wisconsin-Madison. The brain is constantly changing in response to environmental factors, he says, and the article "reflects one of the first efforts to apply this conceptual framework to techniques to enhance qualities that we have not thought of as skills, like well-being. Modern neuroscience research leads to the inevitable conclusion that we can actually enhance well-being by training that induces neuroplastic changes in the brain. " Brains change all the time, Davidson emphasizes.

Debunking the Right-Brain Creativity Myth. What's the Latest Development?

Debunking the Right-Brain Creativity Myth

The idea that creative people are somehow 'right-brained' is a myth, according to recent research completed at the University of Southern California. In a study, a group of subjects were given a creative task—rearranging a circle, a C and an 8 to create a new image—and non-creative task—mentally fitting together geometric shapes to form a square or rectangle. The later task, which requires spatial processing but not necessarily creativity, stimulated tissue in the brain's left hemisphere while the creative task involved the entire brain. What's the Big Idea? While the left hemisphere of your brain is typically thought to control mathematical and logical processes, it is essential to solving creative problems, as well.

Depression Is Linked to Hyperconnectivity of Brain Regions, a New Study Shows

The public has waited for over five weeks for a glimpse into the mind of South African Paralympian Oscar Pistorius, who is currently in the witness box in Pretoria’s North Gauteng High Court to provide evidence and defend himself in the murder trial of his girlfriend Reeva Steenkamp, whom he shot and killed on Valentine’s Day last year. The six-time gold medalist was scheduled to be sworn in at the beginning of March, but the trial was postponed due to the illness of one of the judge’s assessors. The moment everything changed Sobbing uncontrollably after hours of exhaustive testimony on Tuesday, Pistorius detailed the events proceeding the moment that he put four bullets through his bathroom door, killing his 29-year-old girlfriend. “She rolled over to me and said ‘Can't you sleep, my baba?’” ‘Besotted’ with Reeva.

Michael Taft: Hardwired for the Mystical? The gap between atheists and the religious seems at times to be an impossible divide, almost as if believers and non-believers come from different species.

Michael Taft: Hardwired for the Mystical?

What separates the secular from the sacred? An "Ask the Brains" question on the Scientific American site recently inquired as to any differences between the brain of an atheist and the brain of a religious person. Andrew Newberg, the director of research at the Myrna Brind Center of Integrative Medicine at Thomas Jefferson University and Hospital in Philadelphia, responded that, yes, in fact, there are some small but perceptible differences between the brains of believers and non-believers. Rewiring Your Brain for Healthy Empathy: Acquiring a Voltmeter. In the scheme of "rewiring your brain for love," one of the benefits of mindfulness practice when it comes to relationships could be thought of as acquiring a voltmeter -- that quality of empathy that allows you the ability to accurately read the voltage between you and your partner.

I've posted below an introduction to different levels of empathy, and how they can serve or undermine your relationships, which I hope you'll find useful. Acquiring a Voltmeter: Empathy. Group settings can diminish expressions of intelligence, especially among women, study finds. Research has found that small-group dynamics -- such as jury deliberations, collective bargaining sessions, and cocktail parties -- can alter the expression of IQ in some susceptible people.

Group settings can diminish expressions of intelligence, especially among women, study finds

In the classic film "12 Angry Men," Henry Fonda's character sways a jury with his quiet, persistent intelligence. But would he have succeeded if he had allowed himself to fall sway to the social dynamics of that jury? Research led by scientists at the Virginia Tech Carilion Research Institute found that small-group dynamics -- such as jury deliberations, collective bargaining sessions, and cocktail parties -- can alter the expression of IQ in some susceptible people.

"You may joke about how committee meetings make you feel brain dead, but our findings suggest that they may make you act brain dead as well," said Read Montague, director of the Human Neuroimaging Laboratory and Computational Psychiatry Unit at the Virginia Tech Carilion Research Institute, who led the study. 1. 2. 3. 4. 5. 6. Your Brain On Psilocybin Might Be Less Depressed : Shots - Health Blog. Hide captionThis could be your forest on psilocybin. Baxterclaus/Flickr This could be your forest on psilocybin. Magic mushrooms are said to blow your mind, but the hallucinogenic chemical psilocybin, the active ingredient, actually reins in key parts of the brain, according to two new studies. The memorably vivid emotional experiences reported by mushroom users may flourish because the parts of the brain suppressed by psilocybin usually keep our world view tidy and rational. And since the brain area affected by psilocybin can also be out of whack in mental health problems such as depression, the researchers speculate that the drug may turn out to be useful in treating mental illness.

Political Divisions Between Conservatives, Liberals Mirror Reactions To Negative Stimuli. This Is Your Brain During Orgasm. By Kayt Sukel Editor's Note: A writer by trade, Kayt Sukel volunteered to masturbate in an MRI scanner for science. The point of the study? Neuroscientist Barry Komisaruk and sex therapist Nan Wise wanted to know what exactly goes on in the brain when a woman orgasms. Could the sensory cortex be activated by thought alone, they wondered, opening doors for treatments for people unable to orgasm through genital stimulation?

Brain shifts quickly when using a sling or cast. Using a sling or cast after injuring an arm may cause your brain to shift quickly to adjust, according to a study published in the January 17, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology.

The study found increases in the size of brain areas that were compensating for the injured side, and decreases in areas that were not being used due to the cast or sling. "These results are especially interesting for rehabilitation therapy for people who've had strokes or other issues," said study author Nicolas Langer, MSc, with the University of Zurich in Switzerland. "One type of therapy restrains the unaffected, or "good," arm to strengthen the affected arm and help the brain learn new pathways. This study shows that there are both positive and negative effects of this type of treatment. " Your Storytelling Brain. With rendition switcher Michael Gazzaniga : Some people, for instance, love the metaphors that come out of, say, literature and the arts and think that you want to leave those whole and untouched by an analysis as to why we may like those metaphors or why those metaphors seem to help our thinking or any of a number of questions.

And there’s a sense that if someone goes in and assesses that situation and gives a biologic dimension to why we do like those things that somehow it’s all diminished by that. And that’s just not true. In my early part of my career - and it continues - I studied patients who had their two brains disconnected. Christmas brain lectures available worldwide.
