The predisposition of human beings toward spiritual feeling, thinking, and behaviors is measured by a supposedly stable personality trait called self-transcendence. Although a few neuroimaging studies suggest that neural activation of a large fronto-parieto-temporal network may underpin a variety of spiritual experiences, information on the causative link between such a network and spirituality is lacking. Combining pre- and post-neurosurgery personality assessment with advanced brain-lesion mapping techniques, we found that selective damage to left and right inferior posterior parietal regions induced a specific increase of self-transcendence. Therefore, modifications of neural activity in temporoparietal areas may induce unusually fast modulations of a stable personality trait related to transcendental self-referential awareness. These results hint at the active, crucial role of left and right parietal systems in determining self-transcendence and cast new light on the neurobiological bases of altered spiritual and religious attitudes and behaviors in neurological and mental disorders.

Mauro Morales picks his way through mesquite trees and prickly pear cacti. The 65-year-old cautiously steps around a thicket of tasajillo, or rattail cactus, just down the road from his small ranch near Rio Grande City. Tasajillo thorns stick you like a fish hook, he says. Then there’s the cola seca—the rattlesnake—another job hazard.
“We’re far enough from a hospital that you probably wouldn’t make it if you got bit,” he says in a quiet voice, as though a snake might take his words as an invitation to strike.
Morales has been wandering through the chaparral for half an hour, staring at the ground. He combs over small rocks with a stick. Finally, he spots a greenish knob, sprouting out of the ground under the tasajillo thicket.
“There’s some medicine, right there,” he says. It’s a lone peyote button, about an inch in diameter, way too small to harvest. It’ll be another five years before this peyote is mature. As he navigates the hostile flora, he points to three more small peyote plants, all of them too young to cut.
“I used to collect as much in a week as I now do in a month,” he says. “I don’t know what’s going to happen to the medicine.”
An experimental study that treats PTSD veterans with the drug MDMA could make life after war a lot more livable.
“We need to be positioning ourselves now to provide the assistance that our veterans need,” said House Committee on Veterans’ Affairs chairman Bob Filner (D-CA) during a hearing, called “Stopping Suicides: Examining the Mental Health Challenges Facing the Department of Veterans Affairs,” held in December 2007. “Not only for those brave men and women who are returning home from Iraq and Afghanistan, but also for our veterans from previous conflicts. We cannot afford to put this issue off.”
Filner’s choice of words is instructive, as are his sentiments: With upwards of 25 million veterans in the United States, not counting those overseas in the morally murky theater of Iraq and Afghanistan who may return home sometime after the 2008 presidential election, that’s a lot of assistance and funding needed to head off what he called a “rate of veteran suicide [that] has reached epidemic proportions,” to the point that it has doubled the suicide rate of civilians. Safeguards already put into place have failed, for a variety of reasons, and given the severity of the mental and physical problems carried by returning soldiers, some daring out-of-the-box thinking is not only desperately needed, but required.
Enter the Multidisciplinary Association for Psychedelic Studies (MAPS), and its currently funded trials using 3,4-methylenedioxy-N-methamphetamine—otherwise known as MDMA, or ecstasy—to treat post-traumatic stress disorder (PTSD). Although the U.S. Army had carried out lethal dose studies of MDMA back in the 1950s, work which was not classified until the close of the 1960s, it was only centered on animals and was mixed in with a variety of other compounds. At the closure of that research, MDMA languished in clinical obscurity until its rise as a club drug in the ‘80s and ‘90s brought it the kind of attention that dooms better drugs to Schedule I classifications—that is, illegality—and lesser drugs to approval by the Food and Drug Administration (FDA). But MAPS founder and president Rick Doblin became aware of MDMA in 1982, and since then has been convinced of its therapeutic uses. Accordingly, his organization has coordinated and/or funded recent studies into MDMA treatment of PTSD and has its eyes set on a higher goal.
“We’re looking to make MDMA into a prescription medication in the United States, United Kingdom and elsewhere,” he explained by phone.
Life is everywhere in the upper Amazon wilderness. Life that creeps, life that crawls, life that slithers, sprouts, burrows, scurries and slinks—and dies. The dank odors of alternating rot and genesis rise from the mulching forest floor. My Deet-fortified insect spray battles swarms of blood-mad mosquitoes to a draw. The air is fat with syrupy humidity, and I am sweating like an icicle in the sun.
Nature is on fast-forward here. Trees—palms, laurels, kapoks, mahoganies, bamboos, acacias, figs, balsas, cedars—jostle each other in the search for a share of the sunlight; they grow to enormous heights and spread their foliage like a green umbrella at the top. Lianas, tropical climbing plants, wind themselves like boa constrictors around the tree trunks and arch themselves in great loops as they, too, struggle upward for a glimpse of light. The trees become parasites, and giant orchids seed themselves in branches 60 feet from the ground. The general effect is of a an impenetrable fecund, living wall.
Amid this vast assortment of life, creatures use stunts and flim-flam to befuddle or repel predators, lure prey, seduce mates and gobble food. Caterpillars masquerade as snakes, plants imitate the smell of rotting meat to attract flies as pollinators, and trees rely on fish to distribute their seeds when the rivers flood.
It’s a jungle out here.
Psychologists at Harvard University have developed a new method to study extrasensory perception that, they argue, can resolve the century-old debate over its existence. According to the authors, their study not only illustrates a new method for studying such phenomena, but also provides the strongest evidence yet obtained against the existence of extrasensory perception, or ESP.
The research was led by Samuel Moulton, a graduate student in the department of psychology in the Faculty of Arts and Sciences at Harvard University with Stephen Kosslyn, John Lindsley Professor of Psychology at Harvard and was published in the Jan. 2008 issue of the Journal of Cognitive Neuroscience. The scientists used brain scanning to test whether individuals have knowledge that cannot be explained through normal perceptual processing.
“If any ESP processes exist, then participants’ brains should respond differently to ESP and non-ESP stimuli,” explains Moulton. “Instead, results showed that participants’ brains responded identically to ESP and non-ESP stimuli, despite reacting strongly to differences in how emotional the stimuli were and showing subtle, stimulus-related effects.”
Mind-altering psychedelics are back—but this time they are being explored in labs for their therapeutic applications rather than being used illegally. Studies are looking at these hallucinogens to treat a number of otherwise intractable psychiatric disorders, including chronic depression, post-traumatic stress disorder, and drug or alcohol dependency.
The past 15 years have seen a quiet resurgence of psychedelic drug research as scientists have come to recognize the long-underappreciated potential of these drugs. In the past few years, a growing number of studies using human volunteers have begun to explore the possible therapeutic benefits of drugs such as LSD, psilocybin, DMT, MDMA, ibogaine and ketamine.
Much remains unclear about the precise neural mechanisms governing how these drugs produce their mind-bending results, but they often produce somewhat similar psychoactive effects that make them potential therapeutic tools. Though still in their preliminary stages, studies in humans suggest that the day when people can schedule a psychedelic session with their therapist to overcome a serious psychiatric problem may not be that far off.
Electrodes have been implanted in the brain of Eric Ramsay, who has been “locked in” – conscious but paralysed – since a car crash eight years ago.
These have been recording pulses in areas of the brain involved in speech.
Now, New Scientist magazine reports, they are to use the signals he generates to drive speech software.
Although the data is still being analysed, researchers at Boston University believe they can correctly identify the sound Mr Ramsay’s brain is imagining some 80% of the time.
In the next few weeks, a computer will start the task of translating his thoughts into sounds.

When Chinese authorities implement a new law this month on the “reincarnation of Living Buddhas,” it will open a new and controversial phase in the looming battle to find a successor for the 72-year-old Dalai Lama.
The Chinese government described the new law as an “important move to institutionalize the management of reincarnation of Living Buddhas,” or lamas, as the monks in senior positions are known in Tibetan Buddhism.
The concept of reincarnation is viewed by non-believers around the world with a considerable degree of scepticism and amusement, but within the context of Tibetan culture it remains a centerpiece in spiritual life.
These Living Buddhas form the core of leadership in Tibetan Buddhism. They constitute a clergy of influential figures who are believed to be continuously reincarnated to pursue their religious work. At the apex of this spiritual elite is the Dalai Lama, which has an unbroken lineage of reincarnations extending 600 years. The current Dalai Lama is considered as the 14th Dalai Lama.
But the new measure has little to do with the esoteric realm of the afterlife and reincarnation. What Beijing is more concerned with has to do with the realm of politics and its political control over the future of Tibet.
The new regulations stipulate the Chinese government’s approval as a requirement in the search and recognition of reincarnated lamas. Though the Dalai Lama is not mentioned directly, the reference to the Tibetan spiritual leader is clear in a provision stating that “the reincarnation of a Living Buddha with a particularly great impact” has to be approved by the top Chinese leaders in Beijing. Otherwise, the government will consider the reincarnation as “illegal or invalid.”
If one leaves aside the last three hundred years of historical experience as it unfolded in Europe and America, and examines the phenomenon of death and the doctrine of the soul in all its ramifications—Neoplatonic, Christian, dynastic-Egyptian, and so on, one finds repeatedly the idea that there is a light body, an entelechy that is somehow mixed up with the body during life and at death is involved in a crisis in which these two portions separate. One part loses its raison d’etre and falls into dissolution; metabolism stops. The other part goes we know not where. Perhaps nowhere if one believes it does not exist; but then one has the problem of trying to explain life. And, though science makes great claims and has done well at explaining simple atomic systems, the idea that science can make any statement about what life is or where it comes from is currently preposterous.
Buddhist philosophy and the practice of meditation continues to have a large influence on current Western thought about psychological treatment. Mindfulness is growing into an entire field of anxiety treatment, Acceptance and Commitment Therapy is making waves with CBT therapists, and now it appears that meditation can improve attention. It is still early, but meditation now shows promise for treatment of ADHD and other attention problems.
