(NaturalNews) Is it possible to sort of "rewire" your brain so you
can better control imposing symptoms of depression and angst? The short answer,
according to recent new research, is yes, and it all it takes in large
part is some "mindfulness meditation."
According to a study which appeared more than a year-and-a-half ago, in the
January 2011 journal of Psychiatry Research: Neuroimaging, a team led by
Massachusetts General Hospital (MGH) researchers reported that an eight-week
program called mindfulness meditation was able to make measurable changes in
parts of the brain associated with memory, sense of self, empathy and stress.
The study is the first to document meditation-created changes to the brain.
"Although the practice of meditation is associated with a sense of
peacefulness and physical relaxation, practitioners have long claimed that
meditation also provides cognitive and psychological benefits that persist
throughout the day," said the study's senior author, Sara Lazar, PhD, of
the MGH Psychiatric Neuroimaging Research Program.
"This study demonstrates that changes in brain structure may underlie some
of these reported improvements and that people are not just feeling better
because they are spending time relaxing," she said.
Documented physical changes in the brain
In previous studies, Lazar's group and others discovered structural differences
between brains of experienced practitioners of meditation and those who had no
history of it. In particular, researchers observed a thickening of the cerebral
cortex in regions associated with attention and emotional integration, says a
summary of the study at Science Daily. Those earlier studies, however,
were unable to discover a link between the physical cortex changes and
meditation.
That all changed with Lazar's latest study. In it, she and her team took MRIs of
the brain structure of 16 participants in the study two weeks before and two
weeks after they took part in the eight-week program at the University of
Massachusetts Center for Mindfulness.
Besides weekly meetings which included practicing mindful medication - a
practice that focuses on nonjudgmental awareness of feelings, sensations and
state of mind - participants also were exposed to audio recordings of guided
meditation practice and were asked to keep track of how much time they spent
meditating each day. For comparison, MRIs were taken of a control group of non-meditators
over a similar period of time.
Those who meditated did so for an average of 27 minutes each day, according to
the research team, practicing mindfulness exercises. Their subsequent responses
to a mindfulness questionnaire as the study progressed indicated strong
improvements compared to pre-study responses.
An analysis of MRIs that focused on regions where meditation-associated
differences were found in earlier studies showed increased brain densities in
the hippocampus, which is known to be important for learning and memory, as well
as structures associated with self-awareness, compassion and introspection.
None of the changes, however, were seen in the control group.
"It is fascinating to see the brain's plasticity and that, by practicing
meditation, we can play an active role in changing the brain and can increase
our well-being and quality of life," Britta Holzel, PhD, first author of
the paper and a research fellow at MGH and Giessen University in Germany,
said.
"Other studies in different patient populations have shown that meditation
can make significant improvements in a variety of symptoms, and we are now
investigating the underlying mechanisms in the brain that facilitate this
change," she added.
Mindful meditation's increased brain benefits becoming better known
Other researchers were equally enthusiastic.
"These results shed light on the mechanisms of action of mindfulness-based
training," said Amishi Jha, PhD, a University of Miami neuroscientist
who investigates mindfulness-training's effects on individuals in high-stress
situations, who was not involved in the study."
They demonstrate that the first-person experience of stress can not only be
reduced with an eight-week mindfulness training program but that this
experiential change corresponds with structural changes in the amygdala, a
finding that opens doors to many possibilities for further research on MBSR's
potential to protect against stress-related disorders, such as post-traumatic
stress disorder," he said.
This research appears to be similar to a separate body of work that has shown
that with as few as 11 hours of mindful meditation, the white matter of the
brain that aspartame destroys, can begin to grow back.
In the last paragraph of the referenced article it states"
"This research appears to be similar to a separate body of work that has shown that with as few as 11 hours of mindful meditation, the white matter of the brain that aspartame destroys, can begin to grow back."
Here's an excellent article by Mercola on how aspartame destroys brain cells. Of course aspartame is found in everything as a substitute for sugar.

How Does Aspartame Damage Your Brain?
Consuming a lot of aspartame may inhibit the ability of enzymes in your brain to function normally, according to a new review by scientists from the University of Pretoria and the University of Limpopo.Aspartame is a poison
that does not belong in your body, and this is not an exaggeration. Yet, this
toxic substance is consumed by over 200 million people around the world and is
found in more than 6,000 products.
Everything from soda and chewing gum to desserts, yogurt, and even some vitamins
and cough drops contain it.
When you drink, say, a can of diet soda sweetened with aspartame, what are you
REALLY consuming? Here’s a breakdown of aspartame’s three chemicals: the
amino acids aspartic acid and phenylalanine, and methanol.
1. Aspartic acid (40
percent of aspartame)
Aspartate acts as a neurotransmitter in your brain by facilitating the
transmission of information from neuron to neuron. Too much aspartate in your
brain kills certain neurons by allowing the influx of too much calcium into your
cells. This influx triggers excessive amounts of free radicals, which kill your
cells.
The neural cell damage that can be caused by excessive aspartate is why Dr.
Russell Blaylock refers to them as "excitotoxins." They
"excite" or stimulate your neural cells to death.
Now, when aspartic acid is consumed, it significantly raises your blood level of
aspartate, which leads to a high level of those neurotransmitters in certain
areas of your brain, where they slowly begin to destroy neurons.
Your brain cells could be dying right now, but you likely would not notice the
symptoms until 75 percent or more are gone. Then, chronic illnesses such as the
following, which may by caused by long-term exposure to excitatory amino acid
damage, may occur:
2. Phenylalanine (50
percent of aspartame)
Phenylalanine is an amino acid normally found in your brain, however people with
the genetic disorder phenylketonuria (PKU) cannot metabolize phenylalanine. This
leads to dangerously high -- and sometimes lethal -- levels of phenylalanine in
your brain. It has been shown, though, that ingesting aspartame, especially
along with carbohydrates, can lead to excess levels of phenylalanine in your
brain even if you do not have PKU.
Even consuming aspartame one time has been found to raise your blood levels of
phenylalanine. What’s the risk of this?
Excessive levels of phenylalanine in your brain can cause the levels of
serotonin in your brain to decrease, leading to emotional disorders such as
depression. It can also cause schizophrenia or make you more susceptible to
seizures.
3. Methanol (aka wood
alcohol) (10 percent of aspartame)
Methanol/wood alcohol is a deadly poison, and the absorption of methanol into
your body is sped up considerably when free methanol is ingested. Well, free
methanol is created from aspartame when it is heated to above 86 degrees
Fahrenheit (30 Centigrade). This would occur when an aspartame-containing
product is improperly stored (in the sun, for instance) or when it is heated,
such as part of a "food" product like Jello.
Meanwhile, methanol breaks down into formic acid and formaldehyde -- a deadly
neurotoxin -- in your body.
Even the U.S. Environmental Protection Agency (EPA) states that methanol
"is considered a cumulative poison due to the low rate of excretion once it
is absorbed. In the body, methanol is oxidized to formaldehyde and formic acid;
both of these metabolites are toxic."
They recommend a limit of consumption of 7.8 mg/day, but a one-liter
aspartame-sweetened beverage contains about 56 mg of methanol. Heavy users of
aspartame-containing products consume as much as 250 mg of methanol daily -- or
32 times the EPA limit!
The symptoms of methanol poisoning are numerous and varied. They include:
Do You STILL Believe
Aspartame is Safe?
I could literally go on for days about the many problems plaguing this
artificial sweetener; both the dangers it poses to your health and the blatant
greed and manipulation that got it on the market.
That is why I spent years researching and writing Sweet Deception. It is the
most comprehensive book on the market addressing this issue, and if you or your
loved ones drink diet beverages or eat diet foods, please read it sooner rather
than later.
I also highly recommend watching Sweet Misery, which is part documentary, part
detective story that sheds much-needed light on the controversy surrounding
aspartame.
Folks, aspartame is not your friend. It is actually responsible for 80-85
percent of the food complaints registered with the FDA!
Aside from the damage it can do to your brain, aspartame can cause cancer. One
well-controlled, peer-reviewed, SEVEN-year study even found that as little as 20
mg per day can cause cancer in humans.
One 12-ounce diet soda contains about 180 mg of aspartame, so you do the math on
that risk!
If you have NutraSweet or Equal packets in your home, I urge you to get rid of
them. About the only good use for them I’ve heard about is using them to kill
ants in your kitchen.
And if you’re consuming diet foods or drinks of any kind, toss those as well.
Your health will be much better off for it.
If you find you’re still having sweet cravings or are having a hard time
giving up your diet soda, Turbo Tapping is a simple tool to help you get rid of
your soda addiction in a short period of time. And in the case of aspartame,
getting it out of your diet can’t come fast enough.
If you have experienced a reaction to any aspartame product, report it by
calling the FDA Consumer Complaint Coordinator in your area.
