Meditation Gives Brain a Charge, Study Finds
By Marc Kaufman

Brain research is beginning to produce concrete evidence for something that Buddhist practitioners of meditation have maintained for centuries: Mental discipline and meditative practice can change the workings of the brain and allow people to achieve different levels of awareness.
...
Scientists used to believe the opposite -- that connections among brain nerve cells were fixed early in life and did not change in adulthood. But that assumption was disproved over the past decade with the help of advances in brain imaging and other techniques, and in its place, scientists have embraced the concept of ongoing brain development and "neuroplasticity."
Davidson says his newest results from the meditation study, published in the Proceedings of the National Academy of Sciences in November, take the concept of neuroplasticity a step further by showing that mental training through meditation (and presumably other disciplines) can itself change the inner workings and circuitry of the brain.
The Dalai Lama ultimately dispatched eight of his most accomplished practitioners to Davidson's lab to have them hooked up for electroencephalograph (EEG) testing and brain scanning. The Buddhist practitioners in the experiment had undergone training in the Tibetan Nyingmapa and Kagyupa traditions of meditation for an estimated 10,000 to 50,000 hours, over time periods of 15 to 40 years. As a control, 10 student volunteers with no previous meditation experience were also tested after one week of training.
The monks and volunteers were fitted with a net of 256 electrical sensors and asked to meditate for short periods. Thinking and other mental activity are known to produce slight, but detectable, bursts of electrical activity as large groupings of neurons send messages to each other, and that's what the sensors picked up. Davidson was especially interested in measuring gamma waves, some of the highest-frequency and most important electrical brain impulses.
Both groups were asked to meditate, specifically on unconditional compassion. Buddhist teaching describes that state, which is at the heart of the Dalai Lama's teaching, as the "unrestricted readiness and availability to help living beings." The researchers chose that focus because it does not require concentrating on particular objects, memories or images, and cultivates instead a transformed state of being.
Davidson said that the results unambiguously showed that meditation activated the trained minds of the monks in significantly different ways from those of the volunteers. Most important, the electrodes picked up much greater activation of fast-moving and unusually powerful gamma waves in the monks, and found that the movement of the waves through the brain was far better organized and coordinated than in the students. The meditation novices showed only a slight increase in gamma wave activity while meditating, but some of the monks produced gamma wave activity more powerful than any previously reported in a healthy person, Davidson said.

Well if your having Delta Rhythm while your awake, I have some bad news for you:
High delta wave activity during the waking state is not common in healthy adults. However, multiple studies have indicated the presence of increased delta activity in adults during states of intoxication or delirium and in those diagnosed with dementia or schizophrenia.
You are not supposed to have Delta Wave as an adult, other then when you are asleep. Delta waves are also supposed to decline with age, starting in adolescence.
PS…. I run EEG, and Sleep EEG, and I am not buying that is anything other then snake oil.

Ahh, because nothing can enlighten us more as to what's really going on than a machine connected to a brain via some sticky electrodes...
In my opinion, the only thing more ludicrous than using a machine to determine what's going on in someone's head is putting any amount of faith in what another human interprets the machine-collected data to mean.
For some, it's just common sense. Others however, seem to have an inherent desire to reject the concept of "reality is perception". After all, any perceived benefit, is a benefit in and of itself.
For years, doctors tried, unsuccessfully to relieve me of my ailments. When I explained to them that I had found relief in several forms of "alternative" treatment, I was promptly told "that can't help you... if anything it's a placebo effect". Do I care if it's a "placebo" effect? Not in the least. I still benefit from the effect, whether it's chemical, mechanical, or simply suggestive.
This topic reminds me of the saying "The delusion of man is that reality is not an illusion".
In summation, what we perceive to be real, is real. Whether or not it's "real" to someone else is completely irrelevant. If someone fills their ears with tones and beats, and experiences some life improvement, who are you to tell them that it's not real. It's like sticking someone with a knife and telling them it doesn't cause them any discomfort, simply because you have a higher tolerance for pain.
Contrary to popular belief, reality is subjective.

Maybe your inducing some type of self hypnosis, maybe your the one in ten million special people who this works on, who knows.

Now all we're asking is, reconsider your position. Everyone should be willing to do this at all times, but unfortunately we know that the opposite is almost always the case, that people are afraid of new knowledge and understanding and cling defensively to old ideas as if they're mentally territorial.

Did you see the Washington Post article I just cited?
The brain consists of nerve cells or neurons (and glial cells) which are interconnected, and learning may happen through changing of the strength of the connections between neurons, by adding or removing connections, or by adding new cells. "Plasticity" relates to learning by adding or removing connections, or adding cells.

The "Washington Post," "University of Wisconsin," and "National Academy of Sciences" are all "authorities" that "normal" people respect academically. So obviously there is a schism in thought here that goes all the way up the ladder, and all you phony "experts" don't know what in the hell you are really all talking about.

So you want to make it fit, so you can tell us all these things about EEG machines since that's what you know about, right? I know, it's ok.

Or maybe you are just so stubborn that you don't even want to consider that you're wrong.

You can't expect to learn everything from running an EEG machine on people all day.

Well if what you are posting is true, it still discounts nothing I have stated as obviously even the UC Stanford cannot understand why this supposedly works on you. The reason for this bafflements is that it is considered snake oil by anyone with experience in the field. Maybe your inducing some type of self hypnosis, maybe your the one in ten million special people who this works on, who knows. Let us know what they find out AFTER they run your new set of studies, I look forward to reading it. I am glad to hear that it works for you, but the reality is, is it actually the sounds that are causing the change.
Transcranial magnetic stimulation (TMS) is a noninvasive method to excite neurons in the brain: weak electric currents are induced in the tissue by rapidly changing magnetic fields (electromagnetic induction). This way, brain activity can be triggered with minimal discomfort, and the functionality of the circuitry and connectivity of the brain can be studied.
A large number of studies with TMS and rTMS have been conducted for a variety of neurological and psychiatric conditions but few have been confirmed and most show very modest effects, if any. Some conditions which have been reported to be responsive to TMS-based therapy are:
Stroke
Nonfluent aphasia [9]
Tinnitus[10]
Parkinson’s Disease
Dystonia
Amyotrophic lateral sclerosis
Epilepsy
Migraine[11]
Dysphasia
Hemispatial neglect
Major depression (rTMS therapy for drug-resistant depression has been approved by Health Canada for clinical delivery since 2002).
Phantom limb
Chronic pain
Obsessive-compulsive disorder
Auditory Hallucinations associated with Schizoaffective Disorders
Fibromyalgia

Furthermore, the brainwave patterns produced by binaural beat brainwave entrainment, these have been recorded by EEG machines and there's a ton of information out there supporting this fact.
Anyway, i suppose it's keeping the thread going, but I'm at a loss as to why someone, in the face of new and voluminous information, would not be willing to admit to having been in error?
