Altar of the Buddha in Indonesia. Theravada style, flooded in green light. The statue looks similar to one in #Borobudur temple holding Dharmachakra mudra (teaching gesture). It differs from complicated and colorful altars of Mahayana and Tantrayana (Vajrayana) Buddhism because the Buddha is not a god but inspiration for our human potential. It consists of a brass periphery for incense and candles, flowers, oil lamps, water bowls, and sacred cremation relics. May 15, 2014 prior azimuth of Moon on Vesak (Dragono Halim/flickr).

Psychedelic Therapy
Psilocyben can treat cancer, anxiety
Research into the therapeutic potential of illegal "psychedelic" drugs to treat an assortment of mainstream mental health conditions is undergoing a modern-day renaissance.

A host of published studies in the field is showing promise for psychedelics, such as psilocybin -- the active ingredient in "magic mushrooms" -- to help treat alcoholism, depression, drug addiction, and severe anxiety caused by serious or terminal illness.

Other studies are finding that MDMA, also known as the party-drug "Ecstasy," may be valuable in treating PTSD (Post Traumatic Stress Disorder).

"These drugs...were researched extensively in the 1950s and the 1960s, through the early '70s," says Dr. George Greer, medical director for the nonprofit Heffter Research Institute, which raises donations for psilocybin studies worldwide. "There were hundreds of studies that were very promising."

But the psychedelic '60s changed all that.

LSD and other hallucinogens, once confined to the lab, exploded into mainstream culture after the pied-piper of psychedelics, Timothy Leary, urged a generation to try LSD and other hallucinogens as a way to "turn on, tune in, drop out." Many followed his advice, some with bad results. And that triggered a backlash that led the federal government to criminalize psychedelic drugs in 1970.

A year later, U.S. President Nixon launched the "War on Drugs" [made famous by right wing sweethearts Pres. Ronald and First Lady Nancy Reagan].

Those measures helped to create a stigma that brought an end to the early phase of psychedelic research, says Rick Doblin, founder the Multidisciplinary Association for Psychedelic Studies (MAPS).

"There is this tendency when drugs become criminalized for their non-medical use, their medical use then subsequently also becomes suppressed," says Doblin.

But since early 2000, a new willingness to look again at these drugs has shifted the research landscape. And thanks to the fundraising efforts of MAPS and the Heffter Research Institute, modern-day psychedelics studies are now happening at top academic research facilities, including Johns Hopkins University, New York University, the University of New Mexico, and UCLA.

"These agents have very broad applicability within psychiatry and can be used for mood disorders, eating disorders, personality disorders," says Dr. Stephen Ross, a psychiatrist and psychedelics researcher at NYU School of Medicine. "They can be used for so many things that our treatment have not improved in recent years."

But the drugs are powerful and must be used with caution, especially since it's believed they can exacerbate serious mental conditions, such as bipolar disorder and schizophrenia. However, used in a supervised setting with trained therapists, these drugs have the potential to offer properly-screened patients much-needed new treatment options.

Psychedelic Science: E for PTSD
"We are not at all referencing our work to the recreational drug-use world, which is rife with potential risks," says Dr. Charles Grob, director of the Division of Child and Adolescent Psychiatry at Harbor-UCLA Medical Center and a pioneer in modern-day psychedelics research. "We are talking about developing a new model...to be used within medicine and psychiatry."

Grob says psychedelics offer a rather unusual paradigm in which many patients are reporting relief with as few as one or two supervised applications of the drugs, used in conjunction with limited psychotherapy.

"This is very different than conventional drug treatment, which, more often than not, administers a drug on a daily basis for weeks, months and even years," Grob says.

And research into these drugs is a bit less conventional as well. Because the Drug Enforcement Agency (DEA) classifies these illegal drugs as "Schedule One" substances -- considered risky with "no currently accepted medical use" -- scientists must adhere to strict protocols when researching them. Those include rules on how the drugs are used, handled, and stored.

But a greater challenge remains financing. So far, the government has yet to fund research into psychedelics. That leaves private donations as the sole source of funding.

Scientists in this field say they believe as more evidence into the varied uses for these drugs is collected and published the government will be more likely to grant research funding requests.

And as more time passes, Grob says, the stigma brought on by the excesses of 1960s counterculture will further fade.

"The '60s are long over. As the Moody Blues used to sing, 'Timothy Leary is dead'…and many of those with whom he fought have also exited," Grob says, "It's a new world and there is a greater need than ever for more effective treatment models for individuals for whom our conventional treatment models are often sorely lacking."

L.A. Festival of Books (April 12-13, 2014)

Ashley Wells, Seven, Pat Macpherson, CC Liu, Wisdom Quarterly; LATIMES.com; KPFK.org
The Los Angeles Times hosts the annual Festival of Books for all readers, free at USC
http://events.latimes.com/festivalofbooks/

Books, books, so many books to read, to skim through on Kindle, to treasure in acid-free paper. Musty and crinkly, artsy and orthogonal, look at our library! We'll never read these...but we will reference them. We edit (see below), we cite (see at left), we treasure, and sleep on like Edgar Cayce (now David Wilcock) imbibing and absorbing information and knowledge -- maybe even a little wisdom. It's a dying art, maybe even a lost one, reading for the witty and well-read. But there are those great ones with all the nice pictures and the filthy ones that come in half a century of shades. Any how, here's a whole FESTIVAL of books and reading brought to us courtesy of the Los Angeles Times and USC.

Harvard University's Professor Anne Harrington (Ph.D., Oxford University) discusses the relationship between Tibetan Buddhism (Vajrayana) and the brain. The presentation was hosted by the Center for the Study of Religion and Psychology at Boston University's Danielsen Institute.
 
Want me to concentrate or bliss out? (MR)
She refers to the research of the University of Wisconsin's Dr. Richard Davidson on the brain functions of Buddhist monastics during long periods of meditation as well as American fascination with the Eastern-style of meditation of the human 1960s and 1970s counterculture.
 
She covers Transcendental Meditation (TM) and the Dalai Lama's first visit to the U.S. as well as why he was so important to the West's academic and scientific investigation of mystical meditative states.

Moral Tribes: Emotion, Reason, Gap (forum)

CC Liu, Seth Auberon, Wisdom Quarterly; KPCC FM (scpr.org)
Dr. Joshua Greene, Harvard Moral Cognition Lab, talks about morally-based decision-making and the brain. Although matters of morality are abstract, there are ways of examining brains while we decide, allowing for the collection of data about brain activity in parallel with our decisions. In this way, we can better understand which brain circuits drive different types of decisions, particularly those involving moral judgment.

Why can't we come together on climate change? Should the rich pay higher taxes? Should they use their profits to help desperate strangers on the other side of the world? Do gays have a right to marry? Does a woman with an unwanted pregnancy have a right to choose? Is it wrong to eat animals because we care more about their taste than their pain?

On Thursday, Nov. 14th, explore how we make decisions about such questions as KPCC's science reporter Sanden Totten speaks with guest Dr. Joshua Greene, director of Harvard University's Moral Cognition Lab and author of Moral Tribes: Emotion, Reason, and the Gap Between Us and Them
 
Through a "Me vs. Us" and "Us vs. Them" lens, Dr. Greene takes a penetrating and entirely original look at the ways in which neuroscience and evolution guide our moral decision-making process.

(TED Talks) "Experience vs. Memory," Nobel laureate and founder of "behavioral economics" Prof. Kahneman reveals how our "experiencing selves" and our "remembering selves" perceive happiness differently. This new insight has profound implications for economics, public policy, and our own self-awareness. He is regarded as the world's most influential living psychologist.

In the tradition of Prof. Daniel Kahneman's Thinking, Fast and Slow, Moral Tribes deftly reveals the science behind our modern thinking and moral dilemmas and offers a new way of looking at and resolving seemingly irresolvable moral issues.

    Is that 6:00 am workout getting in the way of good sleep? Don't think those fat cells won't notice.
     
    A new study published in the Annals of Internal Medicine finds that inadequate shut-eye has a harmful response on our fat cells, reducing their ability to respond to insulin by about 30 percent. 
     
    Over the long-term, this decreased response could set the stage for Type 2 diabetes, fatty liver disease, and weight gain.

    BREAKING NEWS: Reason we sleep discovered!

    (All Things Considered) While the brain sleeps, it clears out harmful toxins, a process that may reduce the risk of Alzheimer's, researchers now say. During sleep, the flow of cerebrospinal fluid to and from the brain increases dramatically, washing away harmful waste proteins that build up between brain cells during waking hours, a study of mice found. "It's like a dishwasher," says Dr. Maiken Nedergaard, a professor of neurosurgery at the University of Rochester and an author of the study in Science. The results appear to offer the best explanation yet of why animals and people need sleep. More (LISTEN)

    The study adds to a growing body of evidence that there's "an intimate relationship between the amount of sleep we get and our ability to maintain a good, healthy body weight," says sleep expert Helene Emsellem, director of the Center for Sleep and Wake Disorders in Chevy Chase, Maryland.
     
    But Americans don't seem to be getting the message that we need seven to nine hours per night. More than 1 in 5 of us, according to a from the Centers for Disease Control and Prevention, is getting six or fewer hours of sleep per night, on average. LISTEN
