How the Brain Creates Out-of-Body Experiences

By Tanya Lewis via LiveScience

astralt_250pxSAN DIEGO — The human mind effortlessly constructs the feeling of inhabiting a body, and now scientists are figuring out how the brain produces that experience.

The findings, presented here Sunday (Nov. 10) at the annual meeting of the Society for Neuroscience, highlight which brain regions are active when a person has an out-of-body experience.

Recent studies have shown that the brain incorporates information from multiple senses and the first-person visual perspective to create a sense of body ownership. But it’s still unclear how the brain perceives the body’s location in space.

In the study, which has not yet been published in a scientific journal, participants lay inside an MRI scanner while wearing a head-mounted display that showed a first-person camera view of another person’s body lying in a corner of the scanner room, with their head either parallel to a wall or perpendicular to it. Researchers from the Karolinska Institutet in Sweden repeatedly touched each participant with an object while simultaneously touching the body shown in the camera view. This gave participants the illusion that the body in the camera view belonged to them.

To heighten the illusion, the researchers used . . .

Global Warming: Heads they win, tails you lose.

By Mason I. Bilderberg (MIB), January 30, 2014

weasel word 02_flat

Let’s start this article by examining the deceptive use of words and phrases and later i will explain how i believe such deceptions are used in the global warming debate.

A few examples of what i mean.

save02_200pxWhat exactly is being promised by a sign in a store window that says, “Save up to 50% on everything in the store?”

Does it mean:

  1. The discount is 50%
  2. The discount is somewhere between 0% and 50%
  3. The discount applies to everything in the store
  4. The discount only applies to some things in the store
  5. Nothing in the store is discounted
  6. All of the above.

Of course the correct answer is “F” – all of the above.

This is a classic case of advertisers intentionaly using deceptive wording to create a false impression. In this case, the meaning of the words “… up to . . .” can mean anything from 0% to 50%, which renders the rest of the statement meaningless. So even if NOTHING in the store is discounted, this sign is technically true.

Though this kind of deceptive wording might be obvious to some, you might be surprised to learn how many people reading such a sign will interpret it to mean everything in the store is heavily discounted. Deception sells.

Another example . . .


nutriSystem_cropped_250px
Look at the NutriSystem ad to the right. NutriSystem ran print ads like this along with TV commercials and the promise-sounding sales pitch, “… lose all the weight you can at Nutri/System for only $199. Don’t wait, call now.”

Wait a second, back up the truck. Did you catch the deception in this pitch?

For only $199 you will lose all the weight you can? I’m sure you see the problem with this wording. So did the Federal Trade Commission (PDF).

If you don’t lose any weight, then this would be all the weight you can lose. See? NutriSystem didn’t lie – you DID lose all the weight you can – now pay $199!!

One more quick example and i’ll move on to global warming . . .


loan_250pxThis used car salesman on the right. Is he guaranteeing you a loan or is he promising to accept your loan application (so he can toss it into the round file)? There’s a big difference.

How about car dealerships that promise “guaranteed credit” or “cash for all trade-ins!”

Do these sales pitches sound like you will get all the credit you need to buy your dream car and maximum dollars for your used car trade-in? Or do they really mean you’ll get $5 of credit at 25% interest and a whopping $10 for your used car trade-in?

Words mean things. How words are used, misused or not used at all (conspicuous by their absence), also has meaning and can give us a glimpse into the motives behind the words.


I was going through some global warming articles about a week ago and i found this statistic in an article from LiveScience.com:

63pct

My gut finds this statistic hard to believe. It just seems too high compared to other polls i’ve seen in the last few years on the same subject. Two years ago it was reported to be about 50%, now it’s reported at 63%? We haven’t seen any warming in over 15 years and the belief in global warming has climbed? Time to investigate.

So i found the survey upon which this statistic is based (Download the PDF) and i found something interesting on page 34 – the definition of global warming as it was defined for the respondents of this latest survey (November 2013):

GW definition

For the purpose of responding to this survey, there are 3 criteria to consider to determine if you are a global warming believer:

  1. If temperatures have increased over the last 150 years,
  2. future temperatures may increase, and
  3. the worlds climate may change as a result.

Recall the “50% off” sign, the NutriSystem ad and the used car salesman ad at the top of this article. Now look at the wording in the above three criteria. There is one word that renders two of the three criteria completely meaningless.

Do you see it?

The weasel word is “may” in the second and third criteria.

“May” is synonymous with “optional” – something may, OR may NOT, occur.

Thus the three criteria above and these three criteria below are exactly the same from a logic standpoint:

  1. If temperatures have increased over the last 150 years,
  2. future temperatures may OR may NOT increase, and
  3. the worlds climate may OR may NOT change.

With the second and third criterias rendered meaningless, the question of whether global warming is real comes down to one, single question:

  • Have temperatures increased over the last 150 years?

As reported in my last global warming article, this is the temperature record for the last 150 years:

The Record_600px

Like asking if the earth is round, answering the question “Have temperatures increased in the last 150 years?” comes down to a simple, objective, recitation of fact:

  • Yes, the squiggly line is higher on the right side of the graph than it is on the left side of the graph.

Because neither the definition used to assess the answer to the question nor the question itself asks the respondent to consider anything beyond the vertical movement of the squiggly line, the answer to the question cannot be construed as agreeing with the more expansive definition of global warming and the theoretical causes:

Spooky Science: Paranormal Beliefs Linked to Fearful Worldview

By Elizabeth Palermo via LiveScience.com

ghostly_173People who believe in ghosts may be more afraid of actual, real-world dangers — things like violent crimes or nuclear war — than are people who don’t hold paranormal beliefs, a new survey finds.

The Survey of American Fear asked people in the United States to divulge the terrors that keep them up at night. For the survey, nearly 1,500 participants responded to questions about 88 different fears and anxieties, ranging from commonplace phobias (like fear of heights) to less tangible concerns (like fear of government corruption). The survey also asked participants about their beliefs concerning paranormal and mythical things, like ghosts, Bigfoot and ancient aliens.

“The reason we ask [about paranormal things] on the survey is that we’re interested in finding out what kind of clusters of beliefs tend to be associated with fear,” Christopher Bader, a professor of sociology at Chapman University in California and leader of the second annual Fear Survey, told Live Science.

ouija-board-gifLast year in the survey, researchers asked questions that gauged the respondents’ scientific reasoning. This was done to find out how the individuals’ knowledge of scientific ideas (how electricity works, why the sun sets in the west, etc.) related to those respondents’ fears. But this year, the focus was on supernatural beliefs, not scientific ones.

Bader and his colleagues found that quite a few Americans hold paranormal beliefs. The most common of these is the belief that spirits can haunt particular places; 41.4 percent of the demographically representative group of participants said they held this belief. A lot of Americans (26.5 percent) also think that the living and the dead can communicate with each other in some way, the survey found.

Many survey participants said  .  .  .

Viral Soda Infographic: How Does Cola Really Affect the Body?

by Rachael Rettner via livescience

coke-glass_250px_150pxAn infographic that breaks down what happens in your body after you drink one Coke has gone viral, but health experts say some information in the graphic is exaggerated.
In addition, while soda is certainly not a healthy food choice, drinking a sugar-sweetened beverage once in a while wouldn’t necessarily make a person unhealthy, the experts said.
“If you’re drinking one soda on occasion … that doesn’t equate to it being necessarily unhealthy,” said Heather Mangieri, a spokesperson for the Academy of Nutrition and Dietetics and owner of the nutrition consulting company Nutrition Checkup in Pittsburgh. “The overall diet quality is what’s important.”
Health experts say the information in this infographic is exaggerated.

The infographic, which appears on the blog the Renegade Pharmacist, details seven changes that happen to the body during the first hour after drinking a Coke, including the effects of ingesting 39 grams of sugar. The information for the graphic was taken from a 2010 article on the website blisstree.com
On the whole, the science presented in the infographic is fairly accurate, said Dana Hunnes, senior dietitian at the Ronald Reagan UCLA Medical Center.
However, some of the wording is exaggerated, Mangieri said. For example  .  .  .

These are two of my own responses on public forums regarding the above infographic:

The guy who made this infographic (Former pharmacist Niraj Naik) is a well known quack, believing in things like:

  • “sound healing” (https://www.youtube.com/watch?v=rZTqRvWTRCk),
  • “scientific prayers”,
  • “spiritually awakening sounds”,
  • “Ayurveda” – a “5,000 year old system of natural healing”,
  • “Trypnaural meditations. Trypnaural meditations feature an advanced form of brainwave entrainment using isochronic tones.”

He is a self-described “marketing expert.” He’s no different than Food Babe, he sells pseudoscience and makes outrageous claims as a way of self-promotion to make money.

His first claim is utter BS:

In The First 10 minutes: 10 teaspoons of sugar hit your system. (100 per cent of your recommended daily intake.) You don’t immediately vomit from the overwhelming sweetness because phosphoric acid cuts the flavour allowing you to keep it down.

  1. There is no “recommended daily intake” of sugar.
  2. According to the American Heart Association (http://tinyurl.com/momm5hu), “sugars are not harmful to the body, our bodies don’t need sugars to function properly. Added sugars contribute additional calories and zero nutrients to food.”
  3. The average 12oz can of Coca Cola has 39 grams of sugar. Ingesting this amount of sugar will NOT make you vomit – with or without phosphoric acid. As an example, most candy bars (see image below) have comparable amounts of sugar and WITHOUT any phosphoric acid and we don’t see people projectile vomiting in candy stores. This is ridiculous.
A Milky Way bar has a comparable amount of sugar as a can of Coca Cola. According to the first claim in the infographic, this amount of sugar (absent any phosphoric acid) should have people projectile vomiting. Why no vomiting? (click image for larger view)

Out-of-Body Experience Is Traced in the Brain

by Tanya Lewis via livescience

What happens in the brain when a person has an out-of-body experience? A team of scientists may now have an answer.

Out-of-Body 722In a new study, researchers using a brain scanner and some fancy camera work gave study participants the illusion that their bodies were located in a part of a room other than where they really were. Then, the researchers examined the participants’ brain activity, to find out which brain regions were involved in the participants’ perceptions about where their body was.

The findings showed that the conscious experience of where one’s body is located arises from activity in brain areas involved in feelings of body ownership, as well as regions that contain cells known to be involved in spatial orientation, the researchers said. Earlier work done in animals had showed these cells, dubbed “GPS cells,” have a key role in navigation and memory.

The feeling of owning a body “is a very basic experience that most of us take for granted in everyday life,” said Dr. Arvid Guterstam, a neuroscientist at the Karolinska Institutet in Sweden, and co-author of the study published today (April 30) in the journal Current Biology. But Guterstam and his colleagues wanted to understand the brain mechanisms that underlie this everyday experience.

Rubber hands and virtual bodies

In previous experiments, the researchers had explored the feeling of being out of one’s body. For example, the researchers developed the so-called “rubber hand illusion,” in which a person wearing video goggles sees a rubber hand being stroked, while a researcher strokes the participant’s own hand (which is out of sight), producing the feeling that the rubber hand is the participant’s own. The researchers have used a similar technique to give people the feeling of having a manikin’s body, or even an invisible body, as they described in a report published last week in the journal Scientific Reports.

In the new study, Guterstam and his colleagues  .  .  .

Ever Wake Up and Think You See a Ghost?

Here’s What’s Happening

by Bahar Gholipour via LiveScience

It was an ordinary night, but Salma, a 20-year-old student at The American University in Cairo, had a particularly frightening experience. She woke up, unable to move a muscle, and felt as though there were an intruder in her bedroom. She saw what appeared to be a fanged, bloody creature that looked like “something out of a horror movie,” standing beside her bed.

She later explained her experience to researchers who were conducting a survey about sleep paralysis, a common but somewhat unexplained phenomenon in which a person awakens from sleep but feels unable to move. Up to 40 percent of people report experiencing sleep paralysis at some point in their lives, and a few, like Salma, hallucinate shadowy intruders hovering over them.

sleep paralysis 903 flipped_250px“Sleep paralysis can be a very frightening experience for some people, and a clear understanding of what actually causes it would have great implications for people who suffer from it,” said Baland Jalal, a neuroscientist at the University of California, San Diego.

Researchers say that sleep paralysis happens when a person awakens during a stage of sleep known as rapid eye movement (REM). People in this stage of sleep are usually dreaming, but their muscles are nearly paralyzed, which might be an evolutionary adaptation that keeps people from acting out their dreams.

It is harder to explain why a subset of people who experience sleep paralysis feel a menacing figure in their room or pressing on their chests.

One possible explanation could be that the hallucination is the brain’s way of . . .

Are Ghosts Real?

Science Says No-o-o-o

The Pseudoscience of Ghost Hunting

Benjamin RadfordBy Benjamin Radford via livescience

If you believe in ghosts, you’re not alone. Cultures all around the world believe in spirits that survive death to live in another realm. In fact, ghosts are among the most widely believed of paranormal phenomena: Millions of people are interested in ghosts, and a 2005 Gallup poll found that 37 percent of Americans believe in haunted houses — and nearly half believe in ghosts.

ghost 820_250pxGhosts have been a popular subject for millennia, appearing in countless stories, from the Bible to “Macbeth,” and even spawning their own folklore genre: ghost stories. Part of the reason is that belief in ghosts is part of a larger web of related paranormal beliefs, including near-death experience, life after death and spirit communication.

People have tried to (or claimed to) communicate with spirits for ages; in Victorian England, for example, it was fashionable for upper-crust ladies to hold séances in their parlors after tea and crumpets with friends. In America during the late 1800s, many psychic mediums claimed to speak to the dead — but were exposed as frauds by skeptical investigators such as Harry Houdini.

It wasn’t until the past decade that ghost hunting became a widespread interest around the world. Much of this is due to Syfy cable TV’s hit series “Ghost Hunters,” now in its 10th season of not finding good evidence for ghosts. The show spawned several spin-offs, including “Ghost Hunters International” and “Ghost Hunters Academy,” and it’s not hard to see why the show is so popular: the premise is that anyone can look for ghosts.ElmerGhost02_250px The two original stars were ordinary guys (plumbers, in fact) who decided to look for evidence of spirits. Their message: You don’t need to be an egghead scientist, or even have any training in science or investigation. All you need is some free time, a dark place and maybe a few gadgets from an electronics store. If you look long enough, any unexplained light or noise might be evidence of ghosts.

The idea that the dead remain with us in spirit is an ancient one, and one that offers many people comfort; who doesn’t want to believe that our beloved but deceased family members aren’t looking out for us, or with us in our times of need? Most people believe in ghosts because of personal experience; they have seen or sensed some unexplained presence.
